what do you have?
I will assume reds because that is what most have. some fish dont like beef heart but most love catfish filets. It really depends how often you feed them.
I have some larger pygos that I feed every few days and they eat great and will eat anything.
Dont do this if they are small because they may try to eat eachother, but if they are bigger, just reduce the amount of feedings and they will eat it.
