Glofish do not require any special food. You will need to be careful not to over feed them, though. Feed a small amount of food once or twice a day. Any left over food pollutes the tank.
Standard flakes for the fish is good enough. It is even better to feed them a variety of foods, including blood worms and other frozen or fresh worms or shrimp.
They eat flakes, frozen, dried, and live food. They like brine shrimp, worms, insects, and most anything. Feed the little fry Infusoria tablets until old enough to eat flakes.
only with a specified fish food!! , they can eat mostly all the fish food that you'll find (worms, shrimps) do not!! feed them with bread it will pollute the aquarium water
