What are the ideal water parameters for guppies and how to achieve them?

One of the most important aspects of keeping your guppies healthy and beautiful is providing them with optimal water quality. Guppies are adaptable fish, but they still have specific requirements for water temperature, pH, hardness, and ammonia, nitrite, and nitrate levels. In this section, we will explain what these parameters are, why they matter, and how to measure and adjust them in your guppy tank.

Temperature

Guppies are tropical fish that thrive in warm water. The ideal temperature range for guppies is 74°F – 82°F (23°C – 28°C). Within this range, you can adjust the temperature slightly depending on your goals. For example, if you want to encourage breeding, you can raise the temperature to 78°F – 80°F (25°C – 27°C). If you want to slow down the metabolism and growth of your guppies, you can lower the temperature to 74°F – 76°F (23°C – 24°C).

To maintain a consistent temperature in your guppy tank, you will need a reliable heater and thermometer. You can choose from different types of heaters, such as submersible, hang-on-back, or inline heaters. Make sure to select a heater that is suitable for the size of your tank and has a thermostat that allows you to adjust the temperature easily. You will also need a thermometer to monitor the temperature in your tank. You can use a digital or analog thermometer, but make sure to place it away from the heater and in a spot where you can read it clearly.

pH is a measure of how acidic or alkaline the water is. It ranges from 0 to 14, with 7 being neutral. Guppies prefer slightly alkaline water, with a pH of 6.8 – 7.8. This pH range is suitable for most guppy varieties and helps maintain their health and coloration.

To measure the pH of your guppy tank water, you will need a pH test kit. There are different types of pH test kits available, such as liquid drops, strips, or digital meters. You can use any of these methods, but make sure to follow the instructions carefully and compare the results with a color chart or a reference value. You should test the pH of your tank water at least once a week or whenever you notice any changes in your guppies’ behavior or appearance.

If the pH of your tank water is too low (below 6.8), you can raise it by using pH buffers or additives that increase the alkalinity of the water. You can also add crushed coral, limestone, or shells to your substrate or filter media, which will slowly release calcium carbonate into the water and raise the pH. If the pH of your tank water is too high (above 7.8), you can lower it by using pH buffers or additives that decrease the alkalinity of the water. You can also add peat moss, driftwood, or almond leaves to your tank, which will release tannins into the water and lower the pH.

Hardness

Hardness is a measure of how much dissolved minerals are present in the water. There are two types of hardness: general hardness (GH) and carbonate hardness (KH). GH measures the total amount of calcium and magnesium ions in the water, while KH measures the amount of carbonate and bicarbonate ions in the water. Both types of hardness affect the health and well-being of your guppies.

Guppies thrive in moderately hard water, with a GH of 8 – 12 dGH and a KH of 8 – 12 dKH. These levels provide enough minerals for your guppies’ bones, scales, and fins, as well as help maintain stable pH levels in your tank.

To measure the hardness of your guppy tank water, you will need a GH and KH test kit. These kits usually come as liquid drops that you add to a sample of water and compare with a color chart or a reference value. You should test the hardness of your tank water at least once a month or whenever you notice any changes in your guppies’ behavior or appearance.

If the hardness of your tank water is too low (below 8 dGH or dKH), you can raise it by using remineralizing agents or additives that increase the GH and KH of the water. You can also add crushed coral, limestone, or shells to your substrate or filter media, which will slowly release calcium and carbonate into the water and raise the hardness. If the hardness of your tank water is too high (above 12 dGH or dKH), you can lower it by using demineralized water, such as distilled, reverse osmosis, or deionized water, to dilute the minerals in the water. You can also add peat moss, driftwood, or almond leaves to your tank, which will release tannins into the water and lower the hardness.

Ammonia, Nitrite, and Nitrate

Ammonia, nitrite, and nitrate are the three main components of the nitrogen cycle in your guppy tank. The nitrogen cycle is a natural process that converts organic waste into less harmful substances. However, if these substances accumulate in high levels, they can cause serious problems for your guppies.

Ammonia is produced by the decomposition of fish waste, uneaten food, and dead plants in your tank. It is highly toxic to guppies and can cause damage to their gills, skin, and organs. Ammonia levels should always be at 0 ppm in your guppy tank.

Nitrite is produced by beneficial bacteria that break down ammonia in your tank. It is also toxic to guppies and can interfere with their oxygen uptake. Nitrite levels should also be at 0 ppm in your guppy tank.

Nitrate is produced by another type of beneficial bacteria that break down nitrite in your tank. It is less toxic than ammonia and nitrite, but it can still cause stress and disease to guppies if it accumulates in high levels. Nitrate levels should be below 20 ppm in your guppy tank.

To measure the ammonia, nitrite, and nitrate levels of your guppy tank water, you will need a test kit for each parameter. These kits usually come as liquid drops that you add to a sample of water and compare with a color chart or a reference value. You should test these parameters at least once a week or whenever you notice any changes in your guppies’ behavior or appearance.

If the ammonia, nitrite, or nitrate levels of your tank water are too high (above 0 ppm for ammonia and nitrite, above 20 ppm for nitrate), you can lower them by performing regular water changes, using a quality filter, and not overfeeding your guppies. You can also add live plants to your tank, which will absorb some of the nitrogen compounds and provide oxygen and shelter for your guppies.

What are the best types of food for guppies and how to feed them properly?

Guppies are omnivorous fish that need a varied and balanced diet to stay healthy and colorful. They can eat a wide range of food, including plant-based and animal-based sources. However, not all food is equally nutritious or suitable for guppies. In this section, we will explore the different types of food that you can offer your guppies, as well as some tips on how to feed them properly.

Types of Food for Guppies

There are four main types of food that you can give your guppies: flake food, pellet food, frozen and freeze-dried food, and live food. Each type has its own advantages and disadvantages, and you should aim to provide a combination of them to ensure a complete and varied diet for your guppies.

Type	Advantages	Disadvantages
Flake Food	– Convenient and easy to use – Contains essential nutrients and vitamins – Comes in different formulas for different needs	– Can lose nutritional value over time – Can pollute the water if overfed – Can be too large for some guppies
Pellet Food	– Compact and concentrated – Contains high-quality protein and other nutrients – Sinks to different levels of the tank	– Can swell up in the guppy’s stomach and cause bloating – Can be too hard or large for some guppies – Can pollute the water if overfed
Frozen and Freeze-Dried Food	– Provides natural and varied food sources – Contains high-quality protein and other nutrients – Retains most of its nutritional value	– Requires thawing before feeding (for frozen food) – Can be expensive or hard to find – Can spoil quickly if not stored properly
Live Food	– Provides natural and varied food sources – Stimulates the guppy’s hunting instincts – Enhances the guppy’s color and health	– Can introduce parasites or diseases to the tank – Can be expensive or hard to find – Can escape or hide in the tank

Some examples of flake food that you can give your guppies are:

TetraMin Tropical Flakes: This is a staple flake food that contains a blend of vitamins, minerals, and antioxidants to support the guppy’s immune system and overall health.
Omega One Super Color Flakes: This is a color-enhancing flake food that contains natural pigments from salmon skins, spirulina, and kelp to boost the guppy’s vibrant colors.
Hikari Fancy Guppy: This is a specially formulated flake food that contains high-quality protein, vegetable matter, and algae to meet the nutritional needs of guppies.

Some examples of pellet food that you can give your guppies are:

New Life Spectrum Small Fish Formula: This is a premium pellet food that contains high-quality protein from krill, squid, and fish meal, as well as natural color enhancers and probiotics to improve the guppy’s digestion and health.
Fluval Bug Bites Tropical Formula: This is a unique pellet food that contains insect larvae as the main ingredient, providing a rich source of protein and other nutrients for guppies.
Aqueon Tropical Granules: This is a slow-sinking pellet food that contains natural ingredients such as shrimp, spirulina, and garlic to provide a balanced diet for guppies.

Some examples of frozen and freeze-dried food that you can give your guppies are:

Brine shrimp: Brine shrimp are small crustaceans that are rich in protein, fat, and carbohydrates. They are one of the best foods for guppies, especially if they are fed live. Brine shrimp can also be bought frozen or freeze-dried, but they may lose some of their nutritional value in the process.
Daphnia: Daphnia are small aquatic animals that are also rich in protein, fat, and carbohydrates. They are another excellent food for guppies, especially for fry. Daphnia can also be bought frozen or freeze-dried, but they may lose some of their nutritional value in the process.
Bloodworms: Bloodworms are the larvae of midge flies that are high in protein and iron. They are a good treat for guppies, but they should not be fed too often as they can cause constipation or bloating. Bloodworms can also be bought frozen or freeze-dried.

Some examples of live food that you can give your guppies are:

Microworms: Microworms are tiny worms that are easy to culture at home. They are high in protein and ideal for feeding guppy fry. Microworms can also be bought online or from local fish stores.
Vinegar eels: Vinegar eels are another type of tiny worms that are easy to culture at home. They are high in protein and ideal for feeding guppy fry. Vinegar eels can also be bought online or from local fish stores.
Grindal worms: Grindal worms are small white worms that are high in protein and fat. They are suitable for feeding adult guppies, but they should not be fed too often as they can cause obesity. Grindal worms can be cultured at home or bought online or from local fish stores.

How to Feed Guppies Properly

Feeding your guppies properly is just as important as choosing the right type of food for them. Here are some tips on how to feed your guppies properly:

Feed your guppies twice a day, once in the morning and once in the evening. Avoid overfeeding them, as this can lead to obesity, water pollution, and health problems. A good rule of thumb is to feed them only as much as they can eat within two minutes.
Vary the type of food that you give your guppies, alternating between flake food, pellet food, frozen and freeze-dried food, and live food. This will ensure that your guppies get a balanced and varied diet that meets their nutritional needs and satisfies their appetite.
Supplement the commercial food that you give your guppies with some fresh or blanched vegetables, such as cucumber, zucchini, lettuce, or spinach. These will provide some extra fiber and vitamins for your guppies, as well as help prevent constipation and bloating.
If you have guppy fry in your tank, feed them more often than the adults, up to four times a day. Give them small and easily digestible food, such as microworms, vinegar eels, brine shrimp, or daphnia. You can also crush some flake food or pellet food into fine powder and sprinkle it into the tank.
Observe your guppies’ behavior and appearance after feeding them. If they seem lethargic, bloated, or have trouble swimming, you may have fed them too much or given them the wrong type of food. Adjust the amount and type of food accordingly until you find the optimal feeding regimen for your guppies.

What are the common guppy diseases and how to prevent and treat them?

Guppies are generally hardy and resilient fish, but they can still fall victim to various diseases and infections. Some of these diseases can be fatal if not treated promptly and properly. Therefore, it is essential to know the common guppy diseases, their symptoms, and how to prevent and treat them.

Common Guppy Diseases

There are many diseases that can affect guppies, but some are more common and serious than others. Here are some of the most common guppy diseases that you should be aware of:

Disease	Symptoms	Causes	Prevention	Treatment
White Spots / Ich	Small white dots on the fish’s body, fins, or gills; scratching or rubbing against objects; loss of appetite; lethargy	Ichthyophthirius multifiliis parasite; introduced by new fish, plants, or decorations; poor water quality; stress	Quarantine new fish, plants, or decorations; maintain good water quality; avoid stressors	Raise water temperature to 80°F for 3-5 days; use medication with malachite green

How to Prevent Guppy Diseases

As you can see from the table above, many guppy diseases have similar causes and prevention methods. The key to preventing guppy diseases is to provide your fish with a clean and healthy environment that minimizes stress and maximizes immunity. Here are some general tips on how to prevent guppy diseases:

Quarantine any new fish, plants, or decorations before adding them to your main tank. This will prevent any potential pathogens from entering your tank and infecting your existing fish. You should quarantine them for at least two weeks and observe them for any signs of illness.
Maintain good water quality in your tank by performing regular water changes and testing. You should change 25-50% of the water every week and use a gravel vacuum to remove any waste or debris from the substrate. You should also test the water parameters (temperature, pH, hardness, ammonia, nitrite, and nitrate) at least once a week and adjust them as needed.
Avoid overcrowding or aggression in your tank by providing enough space and hiding places for your fish. You should follow the rule of one inch of fish per gallon of water and avoid mixing guppies with incompatible or aggressive fish. You should also provide plenty of live plants, rocks, driftwood, or other decorations to create a natural and comfortable environment for your fish.
Feed your guppies a varied and balanced diet that meets their nutritional needs. You should feed them twice a day and only as much as they can eat within two minutes. You should also vary the type of food that you give them, alternating between flake food, pellet food, frozen and freeze-dried food, and live food. You can also supplement their diet with some fresh or blanched vegetables, such as cucumber, zucchini, lettuce, or spinach.
Treat any injuries or wounds on your fish promptly and properly. If you notice any cuts, scrapes, bites, or other injuries on your fish, you should remove them to a quarantine tank and treat them with an antiseptic solution or medication. This will prevent any infection or fungus from developing on the wound and spreading to other fish.

How to Treat Guppy Diseases

If you notice any signs of illness or disease in your guppies, you should act quickly and treat them accordingly. Here are some general steps on how to treat guppy diseases:

Identify the disease and its cause. You should observe your fish carefully and look for any symptoms that indicate a specific disease. You should also check the water parameters and the tank conditions to see if there are any factors that could have triggered the disease. You can use the table above or consult online resources or local experts to help you identify the disease and its cause.
Remove the sick fish to a quarantine tank. You should isolate the sick fish from the rest of the tank to prevent the disease from spreading to other fish. You should set up a quarantine tank with similar water parameters and conditions as the main tank and transfer the sick fish there. You should also disinfect any equipment or tools that you use to handle the sick fish.
Treat the disease with medication or other methods. Depending on the type and severity of the disease, you may need to use medication or other methods to treat it. You should follow the instructions on the medication label or consult online resources or local experts for guidance. You should also monitor the progress of the treatment and adjust it as needed.
Return the fish to the main tank when they are fully recovered. Once the sick fish show no signs of illness or disease for at least a week, you can return them to the main tank. However, you should make sure that the main tank is clean and healthy before doing so. You should also acclimate the fish gradually to avoid any shock or stress.

How to enhance the color and beauty of your guppies with natural methods?

Guppies are one of the most colorful and beautiful fish in the aquarium hobby. They come in a dazzling array of colors, patterns, and shapes that can brighten up any tank. However, sometimes guppies may lose their color or look dull due to various factors such as stress, poor diet, disease, or genetics. Fortunately, there are some natural methods that you can use to enhance the color and beauty of your guppies without resorting to artificial or harmful means. Here are some of the best natural methods that you can try:

Feed your guppies high-quality and varied food

One of the most important factors that affect the color and beauty of your guppies is their diet. Guppies are omnivorous fish that need a balanced and varied diet that contains both plant-based and animal-based food sources. You should feed your guppies high-quality flake food or pellet food that is specially formulated for guppies or tropical fish. These foods contain essential nutrients and vitamins that support the guppy’s health and coloration. You should also supplement their diet with some natural food sources such as live food, frozen food, or freeze-dried food. These foods provide protein and other nutrients that enhance the guppy’s color and growth. Some of the best natural foods for guppies are:

Brine shrimp: Brine shrimp are small crustaceans that are rich in protein, fat, and carbohydrates. They are one of the best foods for guppies, especially if they are fed live. Brine shrimp can also be bought frozen or freeze-dried, but they may lose some of their nutritional value in the process.
Daphnia: Daphnia are small aquatic animals that are also rich in protein, fat, and carbohydrates. They are another excellent food for guppies, especially for fry. Daphnia can also be bought frozen or freeze-dried, but they may lose some of their nutritional value in the process.
Bloodworms: Bloodworms are the larvae of midge flies that are high in protein and iron. They are a good treat for guppies, but they should not be fed too often as they can cause constipation or bloating. Bloodworms can also be bought frozen or freeze-dried.

You should also feed your guppies some fresh or blanched vegetables such as cucumber, zucchini, lettuce, or spinach. These vegetables provide some extra fiber and vitamins for your guppies, as well as help prevent constipation and bloating.

You should feed your guppies twice a day and only as much as they can eat within two minutes. You should also vary the type of food that you give them to ensure a complete and varied diet.

Maintain good water quality and parameters

Another crucial factor that affects the color and beauty of your guppies is the water quality and parameters in your tank. Guppies need clean and healthy water to thrive and show their best colors. You should maintain good water quality by performing regular water changes and testing. You should change 25-50% of the water every week and use a gravel vacuum to remove any waste or debris from the substrate. You should also test the water parameters (temperature, pH, hardness, ammonia, nitrite, and nitrate) at least once a week and adjust them as needed.

The ideal water parameters for guppies are:

Temperature: 74°F – 82°F (23°C – 28°C)
pH: 6.8 – 7.8
Hardness: 8 – 12 dGH
Ammonia: 0 ppm
Nitrite: 0 ppm
Nitrate: < 20 ppm

You should use a heater and a thermometer to maintain a consistent temperature in your tank. You should also use pH buffers or additives to adjust the pH level if it is too high or too low. You should also use remineralizing agents or additives to adjust the hardness level if it is too soft or too hard.

Provide enough light and plants

Lighting is another important factor that affects the color and beauty of your guppies. Guppies need adequate lighting to display their vibrant colors and patterns. You should provide your tank with an aquarium light that mimics the natural daylight cycle. You should also choose a light spectrum that enhances the colors of your guppies. For example, you can use a full-spectrum light or a light with a color temperature of 6500K or higher.

You should also provide your tank with plenty of live plants that can absorb some of the excess nutrients and provide oxygen and shelter for your guppies. Live plants can also create a natural and comfortable environment for your guppies and enhance their color and beauty. Some of the best live plants for guppies are:

Java moss: Java moss is a low-maintenance plant that can grow in any water conditions. It can provide a soft and fluffy carpet for your guppies to swim and hide in. It can also help reduce algae growth and improve water quality.
Anubias: Anubias is a hardy plant that can tolerate low light and high temperatures. It has broad and dark green leaves that can contrast well with the colors of your guppies. It can also provide shade and shelter for your guppies.
Hornwort: Hornwort is a fast-growing plant that can float or be planted in the substrate. It has thin and needle-like leaves that can provide cover and spawning sites for your guppies. It can also help remove nitrates and other toxins from the water.

Avoid stress and aggression

Stress and aggression are two major factors that can affect the color and beauty of your guppies. Stress can weaken the immune system and reduce the pigment production of your guppies, making them look dull and pale. Aggression can cause physical injuries and wounds on your guppies, making them vulnerable to infection and disease.

You should avoid stress and aggression in your tank by providing enough space and hiding places for your guppies. You should follow the rule of one inch of fish per gallon of water and avoid mixing guppies with incompatible or aggressive fish. You should also provide plenty of live plants, rocks, driftwood, or other decorations to create a natural and comfortable environment for your guppies.

You should also maintain a proper male to female ratio of guppies in your tank. Male guppies are more colorful than female guppies, but they are also more aggressive and territorial. They will chase and harass female guppies or other male guppies, causing stress and injury. You should keep one male guppy for every three female guppies to reduce aggression and stress.

Other natural methods

There are some other natural methods that you can use to enhance the color and beauty of your guppies, such as:

Adding natural color enhancers to the water: You can add some natural substances to the water that can enhance the color of your guppies. For example, you can add some almond leaves, peat moss, or driftwood to the water, which will release tannins into the water and create a slightly acidic and soft water condition that is ideal for guppies. Tannins can also enhance the red, orange, and yellow colors of your guppies.
Adding natural color enhancers to the food: You can also add some natural substances to the food that can enhance the color of your guppies. For example, you can add some spirulina, paprika, or turmeric to the food, which will provide some natural pigments that can boost the blue, red, or yellow colors of your guppies.
Breeding selectively: You can also breed selectively to enhance the color and beauty of your guppies. You can choose the most colorful and beautiful male and female guppies in your tank and breed them together. This way, you can increase the chances of producing offspring with similar or better colors and patterns.

How to breed guppies successfully and raise healthy fry?

Guppies are one of the easiest and most rewarding fish to breed in the aquarium hobby. They are prolific breeders that can produce dozens of offspring every month. They also come in a variety of colors, patterns, and shapes that can make your tank look stunning. However, breeding guppies successfully and raising healthy fry requires some knowledge and preparation. Here are some steps that you can follow to breed guppies successfully and raise healthy fry:

Step 1: Select the fish you want to breed

The first step to breeding guppies is to select the fish you want to breed. You should choose healthy and mature guppies that have the colors, patterns, and shapes that you like. You should also consider the genetics and compatibility of the fish you choose. You can breed guppies from the same strain or from different strains, depending on your preference and goals.

Some factors that you should consider when selecting the fish you want to breed are:

Number of fish: Generally, you will want to select one male and two or three female guppies for breeding. When there is a ratio of one to one, the male often becomes aggressive, chasing the female around the tank. With a one to three ratio, the male’s attention is split between three females, making breeding a less stressful process for the females
Color pattern: There are several basic guppy patterns. These include Wild (grey or olive coloring), Albino (light colors or white with red eyes,) Blonde (light colors with black pigment,) and Blue (shimmering blue color.) You can also find guppies with more complex patterns such as Snakeskin (a network of dark lines on a light background,) Cobra (a network of dark spots on a light background,) Tuxedo (a dark body with a light tail,) or Mosaic (a mix of different colors and shapes.) If you choose two fish to breed who have the same color pattern, the fry will also have that color pattern. If you choose two fish with different color patterns, the fry will have a mix of both patterns or a new pattern altogether.
Tail shape: The shape of guppy tails can range from a rounded back fin to a sword-like shape. There are many different shapes and sizes that guppy tails come in, but the most common are the Delta (which is a large triangular shape,) the Fantail (which is shaped like a fan,) the Round tail (which is a small, round shape,) the Swordtail (which has a long extension at the bottom of the tail,) and the Lyretail (which has a split at the end of the tail.) If you choose two fish to breed who have the same tail shape, the fry will also have that tail shape. If you choose two fish with different tail shapes, the fry will have a mix of both shapes or a new shape altogether.

Step 2: Select the breeding tank

The second step to breeding guppies is to select the breeding tank. You should select a 10 to 20 gallon tank with a heater and a gentle filter. You want the filter to be gentle because otherwise the baby guppies (which are called fry) could be sucked up by the filter and killed. If you think your filter is too strong, cover the opening of the filter with sheer tights. The tights will allow the water to be filtered, but will also protect the fry.

Step 3: Set up the tank

The third step to breeding guppies is to set up the tank. You will need to provide some hiding places for the fry after they are born, as well as some plants and decorations for your adult guppies. You will also need to adjust the water parameters and temperature for your guppies’ needs.

Some things that you will need to set up your tank are:

Hiding places for fry: Guppy parents can be cannibalistic and eat their own fry if they get hungry or stressed. Therefore, you will need to provide some hiding places for your fry where they can escape from their parents’ jaws. You can use low-floating plants such as Java moss or spawning mops for this purpose. You can also use some artificial plants or decorations that have small holes or crevices where fry can hide.
Plants and decorations for adults: Guppies like to have some plants and decorations in their tank where they can swim around and explore. Plants can also help improve water quality by absorbing excess nutrients and providing oxygen. Decorations can also add some visual interest and color to your tank. You can use live or artificial plants and decorations, depending on your preference and budget. Some examples of plants and decorations that you can use are Anubias, Hornwort, driftwood, rocks, or caves.
Water parameters and temperature: Guppies need clean and healthy water to thrive and breed. You should maintain the following water parameters and temperature in your tank:
- Temperature: 74°F – 82°F (23°C – 28°C)
- pH: 6.8 – 7.8
- Hardness: 8 – 12 dGH
- Ammonia: 0 ppm
- Nitrite: 0 ppm
- Nitrate: < 20 ppm

Step 4: Introduce the fish to the tank

The fourth step to breeding guppies is to introduce the fish to the tank. You should acclimate the fish to the new water conditions before adding them to the tank. You can do this by floating the bag that contains the fish in the tank for about 15 minutes, then adding some tank water to the bag every few minutes until the bag is full. Then, you can release the fish into the tank.

You should also observe the fish for any signs of stress or disease after adding them to the tank. If you notice any abnormal behavior or appearance, you should remove the fish and treat them accordingly.

Step 5: Wait for the fish to breed

The fifth step to breeding guppies is to wait for the fish to breed. Guppies are very easy to breed, as they will mate on their own without any intervention from you. The male guppy will chase and court the female guppy until she accepts him. Then, he will insert his gonopodium (a modified anal fin) into her vent and transfer his sperm packets (called milt) into her body. This process is called internal fertilization.

The female guppy can store the sperm packets in her body for several months and use them to fertilize multiple batches of eggs. This means that she can give birth to several broods of fry without mating again. The gestation period of guppies is about 21 to 30 days, depending on the water temperature and other factors.

You can tell if a female guppy is pregnant by looking at her abdomen. A pregnant female guppy will have a swollen belly that will grow larger as she approaches her due date. She will also develop a dark spot near her vent called a gravid spot. This spot is actually the eyes of the developing fry inside her body.

Step 6: Remove the fry from their parents

The sixth step to breeding guppies is to remove the fry from their parents. As mentioned before, guppy parents can eat their own fry if they are not separated from them. Therefore, you will need to remove the fry as soon as they are born or even before they are born.

There are two ways that you can remove the fry from their parents:

Use a breeder box: A breeder box is a small plastic box that has slits or holes at the bottom. You can place a pregnant female guppy inside this box and hang it inside your tank. When she gives birth, the fry will fall through the slits or holes and swim away from their mother. This way, you can protect them from being eaten by their mother or other fish in the tank.
Use a separate tank: A separate tank is another option that you can use to remove the fry from their parents. You can either move a pregnant female guppy to a separate tank before she gives birth, or move the fry to a separate tank after they are born. This way, you can provide them with more space and better care than in a breeder box.

Step 7: Raise healthy fry

The seventh and final step to breeding guppies is to raise healthy fry. Fry are very delicate and vulnerable, so you will need to provide them with proper care and attention. Here are some tips on how to raise healthy fry:

Feed them frequently: Fry need a lot of food to grow and develop properly. You should feed them four to six times a day with small and easily digestible food such as microworms, vinegar eels, brine shrimp, daphnia, or crushed flake food.
Maintain good water quality: Fry are very sensitive to water quality, so you should keep their water clean and healthy at all times. You should perform daily partial water changes (10-20%) and test the water parameters regularly. You should also use a sponge
