On How to Raise Guppy Fry Fast

If you want to raise guppy fry quickly and ensure their healthy growth, here are some tips:

  1. Separation: As soon as the guppy fry are born, it’s important to separate them from the adult fish. Guppy fry are susceptible to being eaten by larger fish, including their own parents. Move them to a separate tank or breeding box to provide a safe environment for their growth.
  2. Proper tank setup: Set up a suitable tank for the guppy fry. Use a small tank or breeding box with a sponge filter or air-driven filter to maintain water quality without creating strong currents that could harm the fry. Ensure the water temperature is around 75-80°F (24-27°C) and provide hiding spots such as dense vegetation or artificial structures.
  3. Feeding: Feed them a high-quality diet formulated specifically for fry. You can use commercially available fry food, finely crushed flakes, or infusoria. Feed small amounts multiple times a day to ensure they have enough food without causing water quality issues.
  4. Water quality: Maintaining good water quality is crucial for the health and growth of guppy fry. Perform regular water changes of around 20% every few days to keep the water clean and stable. Optionally use a water conditioner to remove chlorine and other harmful substances from tap water.
  5. Gradual introduction of solid food: As the fry grow, you can gradually introduce finely crushed flakes, baby brine shrimp, or microworms to their diet. These foods provide additional nutrition and help in their development. Monitor their behavior and adjust the feeding routine accordingly.
  6. Growth-friendly environment: Ensure the tank is well-maintained and free from any potential stressors. Avoid sudden temperature fluctuations, excessive noise, and bright lights that could cause stress. Provide a stable and comfortable environment to promote healthy growth.

Remember, each fish’s growth rate can vary, and patience is key. With proper care, feeding, and a suitable environment, you can help your guppy fry grow quickly and thrive.

Food Options

When considering how to raise guppy fry fast, it’s important to provide them with a nutritious and appropriate diet to support their growth and development. Here are some good food options for guppy fry:

  1. Powdered or liquid fry food: Commercially available powdered or liquid fry food specifically formulated for young fish is an excellent choice. These foods often contain a balanced blend of essential nutrients, proteins, vitamins, and minerals necessary for fry growth. Follow the manufacturer’s instructions for feeding quantities and frequency.
  2. Finely crushed flakes: You can crush high-quality flakes into fine particles to make them more manageable for the fry. Ensure the flakes are fresh and free from additives or preservatives. Look for flakes that are specifically designed for fry or small fish.
  3. Newly hatched brine shrimp: Baby brine shrimp (artemia) are a highly nutritious food source for guppy fry. You can hatch brine shrimp eggs at home using a brine shrimp hatchery or purchase pre-hatched brine shrimp from aquarium stores. Feed the newly hatched brine shrimp to the fry, as they are small enough to be easily consumed.
  4. Micro worms: Microworms are another popular live food option for guppy fry. These tiny nematodes can be cultured at home or purchased from specialty stores. Microworms provide a good source of nutrition for the fry.
  5. Infusoria: Infusoria refers to a mixture of microscopic organisms such as protozoa, rotifers, and microalgae. You can culture infusoria at home, and it can serve as a suitable first food for newly hatched fry, as they are small and easily consumed.
  6. Commercial fry foods: Some commercial fish foods are specifically formulated for guppy fry and other small fish species. These foods often come in the form of powders or finely ground pellets, providing a balanced diet for the growing fry. Look for reputable brands and check the ingredients to ensure they contain high-quality nutrients.

When feeding guppy fry, remember to offer small amounts of food multiple times a day, as they have small stomachs and need frequent feeding. Observe their behavior and adjust the feeding routine accordingly to avoid overfeeding or wasting excess food, which can lead to water quality issues.

Variety is key when it comes to feeding guppy fry, as it helps provide a range of nutrients and encourages a well-rounded diet. Incorporating a mix of the above-mentioned food options will help ensure the fry receive the necessary nutrition for healthy growth and development.


In conclusion, raising guppy fry fast requires careful attention to their environment, nutrition, and overall well-being. By following the steps outlined in this guide, you can create an ideal setting for their growth and development. Remember to provide a safe and separate space for the fry, maintain optimal water conditions, and offer a balanced diet. Regular monitoring and maintaining a suitable stocking density are also important factors in promoting rapid growth. While patience is required, with consistent care and attention, you can help your guppy fry thrive and reach adulthood in a relatively short time. Enjoy the rewarding experience of witnessing their transformation and the vibrant colors they will display as they mature.

Happy guppy fry raising!
