Feeding Schedule for Newborn Guppy Fish

Feeding newborn guppy fish can be a rewarding experience, but it's important to know exactly what and how much to feed them to ensure their healthy growth. In this article, we will guide you through the ideal feeding schedule for these baby fishes.

Newborn guppy fish, known as fry, have different nutritional requirements compared to adult guppies. As they are still developing and growing, their food should be smaller and more frequent. Here's a feeding schedule you can follow to provide the best care for your newborn guppy fish:

First Few Days: Infusoria

During the first few days after birth, guppy fry are not yet capable of eating traditional fish food. Instead, they need tiny, live organisms called infusoria. Infusoria can be obtained by soaking a lettuce leaf in clean water and leaving it in a sunny spot for a couple of days. The tiny organisms that grow on the leaf, such as paramecium and rotifers, will become a nutritious food source for the fry.

After 3-4 Days: Newly Hatched Brine Shrimp

Around three to four days after birth, your guppy fry should be large enough to start eating newly hatched brine shrimp. You can purchase brine shrimp eggs from pet stores or hatch them at home using a brine shrimp hatchery kit. Make sure to rinse the newly hatched brine shrimp before feeding them to your fry to remove any debris or shells.

1-2 Weeks Old: Commercial Fry Food

When your guppy fry reach the age of one to two weeks, they can start consuming commercially available fry food. Look for specialized fry food pellets or powdered formulas specifically designed for young fish. These foods are high in protein and contain the essential nutrients needed for optimal growth and development. Crush the pellets into a fine powder or mix the powdered formula with water to create a paste-like consistency that the fry can easily consume.

3-4 Weeks Old: Gradual Introduction to Flakes

As your guppy fry approach the three to four-week mark, you can gradually introduce them to crushed adult guppy flakes. Start by grinding the flakes into smaller pieces that the fry can handle. Over time, you can increase the size of the flakes until they are able to consume the regular-sized ones. It's important to monitor their feeding behavior and ensure that they are able to eat the flakes without any difficulty.

Beyond 4 Weeks: Regular Guppy Food

After the four-week mark, your guppy fry should be capable of consuming regular guppy food. Offer them a balanced diet consisting of high-quality flakes, pellets, and occasional treats such as frozen or live foods. Remember to provide them with a variety of food to ensure they receive all the necessary nutrients for good health.

It's essential to remember that overfeeding can lead to poor water quality and health issues for your guppy fry. Feed them small amounts of food several times a day, making sure to remove any uneaten food after a few minutes. Monitor their growth and adjust the feeding schedule accordingly.

By following this feeding schedule, you can provide your newborn guppy fish with the nutrition they need to thrive. Keep an eye on their growth and behavior to ensure they are healthy and happy. Happy feeding!


When it comes to feeding newborn guppy fish, it is essential to provide them with the right nutrition to promote healthy growth and development. While baby guppies can initially survive on their yolk sac, they will eventually need to be introduced to external food sources. This article will guide you on the recommended food for baby guppy fish.

  • Infusoria: One of the best foods to start with for newborn guppy fish is infusoria. Infusoria are tiny organisms that grow in stagnant water. They are rich in nutrients and perfect for the delicate mouths of baby guppies. To cultivate infusoria, fill a small container with water and place a piece of lettuce, spinach, or a slice of banana in it. After a few days, the water will become cloudy, indicating the growth of infusoria. Transfer a small amount of this water into the tank containing the baby guppies, and they will eagerly consume the tiny organisms.
  • Powdered fish food: Once your baby guppies have grown a bit and are ready for more substantial food, you can introduce them to powdered fish food. This food consists of finely ground flakes that are easier for their small mouths to eat. Before feeding, moisten the powdered food with tank water to create a paste-like consistency. Using a syringe or dropper, carefully release the food into the tank, making sure it is distributed evenly.
  • Newly hatched brine shrimp: Another excellent food option for baby guppy fish is newly hatched brine shrimp. These tiny aquatic crustaceans provide a good source of protein and essential nutrients. You can purchase brine shrimp eggs from pet stores or hatch them at home. To hatch brine shrimp, add the eggs to a container of saltwater and provide aeration. After a day or two, the eggs will hatch, and you can harvest the tiny shrimps using a fine mesh net. Rinse them in freshwater to remove excess salt before feeding them to your baby guppies.
  • Microworms: Microworms are another live food option that baby guppies enjoy. These small nematodes are easy to culture at home. Start by placing a slice of bread or oatmeal in a container and moisten it with water. Sprinkle a small number of microworms on the moist surface and cover the container with a breathable lid. The worms will feed on the bread and reproduce, creating a sustainable food source for your baby guppies. Gently transfer a small amount of microworms to the tank and observe as your guppies eagerly consume them.

Remember to feed your baby guppy fish small amounts multiple times a day, as their stomachs are only capable of holding small quantities. As they grow, gradually introduce them to other appropriate foods such as crushed flakes or finely ground pellet food.

In addition to providing the right food, ensure water quality in the tank remains optimal by performing regular water changes and maintaining suitable temperature and pH levels. With proper nutrition and care, your baby guppies will thrive and grow into healthy adult fish.


Providing a Balanced Diet for Newborn Guppy Fish

Providing a balanced diet is crucial for the healthy growth and development of newborn guppy fish. While they can survive on a diet of commercial fish food, it's important to offer them a variety of nutritious options to ensure optimal health and vibrant coloration. In this article, we will discuss some key considerations when it comes to feeding newborn guppy fish.


Infusoria is a great first food for newborn guppies. It consists of small microscopic organisms that are readily available in freshwater environments. To create an infusoria culture, you can leave a jar filled with water and some plants or vegetables outside for a few days. This will allow microorganisms to grow, providing a constant supply of food for your newborn guppies.

Baby brine shrimp:

After a week or so, you can start introducing baby brine shrimp to the diet of your newborn guppy fish. Baby brine shrimp are highly nutritious and easy to obtain. You can either hatch your own brine shrimp eggs or purchase them from pet stores. Simply place the hatched brine shrimp in a small container and feed them to your guppy fry using a pipette or feeding syringe.


Microworms are another excellent source of nutrition for newborn guppy fish. These tiny worms can be cultured at home using oatmeal or yeast as a medium. Simply sprinkle the microworms on the water surface and watch as the fry eagerly eat them up. Microworms are high in protein and will help promote healthy growth in your guppy fry.

Crushed flakes and pellets:

As your guppy fry grow, you can gradually introduce crushed flakes or pellets into their diet. These commercial fish foods are specifically formulated to provide a balanced diet for fish, and they contain essential nutrients such as proteins, carbohydrates, vitamins, and minerals. Crush the flakes or pellets into small pieces that are easily consumed by the fry.

Vegetable matter:

In addition to live and commercial foods, it's beneficial to offer some vegetable matter to your newborn guppy fish. Finely chopped leafy greens, such as spinach or lettuce, can be blanched and offered to the fry. Vegetables provide fiber, vitamins, and minerals that contribute to overall health and help prevent digestive issues.

Feedings and frequency:

Newborn guppy fish have small stomachs and should be fed small amounts multiple times a day. It's important to monitor their feeding behavior and adjust the quantity of food accordingly. Overfeeding can lead to water quality issues and health problems, so it's best to offer only what the fry can consume within a few minutes.

Water quality:

Proper water quality is essential for the health and well-being of newborn guppy fish. Ensure that their tank is properly filtered, and perform regular water changes to maintain optimal conditions. Uneaten food should be promptly removed from the tank to prevent it from decomposing and affecting water quality.

In conclusion, providing a balanced diet for newborn guppy fish is key to their healthy growth and development. By offering a variety of nutritious foods such as infusoria, baby brine shrimp, microworms, crushed flakes or pellets, and vegetable matter, you can support the overall health and vibrant coloration of your guppy fry. Be mindful of feeding frequency and water quality to ensure the best possible conditions for your newborn guppy fish.
