I've always thought it would be nice to have a breeding setup for fish, as its always fun to breed. I'm planning on having a 50 gallon predator tank with a senegal, peacock eel, and a leaf fish. If i had 1 breeding pair in a twenty, and ten gallon fry tank could this supply my fish with enough feeders to become part of their diet, or only an occasional treat? I've tried breeding guppies, but the fry took too long to grow to a good size to be used as a feeder, and they didn't breed often enough. I ended up deciding the amount of work and time wasn't worth the tiny amount of feeders.
