1. Infusoria (From Day 1 to 7)

For the first week after fries are born or in the early days of their lives, molly fries are too small to eat anything bigger than their mouth opening, which makes Infusoria a perfect choice. Think of Infusoria as a term for those small organisms that the molly fries or other fry, in general, can be fed upon.

They are an excellent food for fry, as they contain all the necessary nutrients for rapid growth and development in the initial days.

It is possible to culture infusoria at home using banana peels, milk, straws, lettuce, or other items.

This microscopic food is ideal for newborn mollies to become healthy adults.

2. Baby Brine Shrimp (Between Days 7 to 21)

Between days 7-21, your Molly fry should be big enough to eat baby brine shrimp. Baby brine shrimp are small, nutrient-rich crustaceans that can be easily cultured at home. They are a great source of protein with a high protein content of 71% and other essential nutrients needed by a growing fry.

Many people prefer to freeze the brine shrimp to kill off or prevent any bacteria and parasites.

You should definitely include this protein-rich food in your molly fry diet.

3. Freeze-Dried & Frozen Foods (From Days 21 to 35)

When your molly fry is 3 weeks old, it can be offered a variety of freeze-dried or frozen foods, such as daphnia, bloodworms, and Vinegar eels. These foods are high in protein and other essential nutrients and will help the development of the fries.

To feed freeze-dried or frozen foods to your fry, thaw the food according to the package instructions but make sure you break it down into small pieces that can fit into a fry’s mouth in small amounts to the fry tank.

4. Worms (From Days 35 to 56)

Around the fifth week of their lives, you can offer your molly fries worms, such as black worms, white worms, grindal worms, and earthworms.

Worms are one of the most popular food choices when it comes to feeding both adult fishes as well as fries, as they contain the essential nutrients that the fish or fries need.

To feed worms to your fry, cut the worms into small pieces and add them to the fry tank.

5. High-Quality Flakes & Pellets (From Days 56 to Onwards)

When your molly babies are big enough (around week 8) that you think they’re not fries anymore, it’s time to feed them some high-quality flakes and pellets. You can crush and sprinkle a small amount of the flakes into the aquarium, or it would be best to turn the big flakes into a fine powder; you can use either a coffee grinder or a mortar and pestle to grind it up. These specially formulated foods are designed to provide a balanced diet for fish.

You can go with a high-quality product like Fluval Bug Bites which have high protein content and essential vitamins and minerals for the fry’s growth.

6. Egg yolk (From Day 1)

The egg yolk can be used as an emergency food if no other food is available. It is a protein and fat-rich food that also contains other nutrients which are good for fry health. However, it is recommended to not only feed the egg yolk, but also to provide live food and other nutritious foods as well.

It is very easy to prepare egg yolk food at home. The process starts with hard boiling an egg. The next step is to remove the egg white and shell because only the yolk part of the egg is essential here. Make a paste of it which you can store in the fridge.

Generally, it is recommended to feed molly fry small amounts of food several times a day; you can stick to the rule of feeding them about 4-5 times a day.
