Depends on how your fishes are. Mine eat a lot. I have 2 pumpkins and they have food 3 times a day. They are my world and I love them dearly. I treat them like family. They are about 1 year now and they definitely have an huge appetite.
Please do not over feed your fish. They can die. Give them a pinch and that's it! They cannot speak or tell you how much they are hurting or are sick so you really have to look at it from their eyes. For my fishes - I give them 3 pinches of food a day and they share that! :)
