My girlfriend has a few angel fish in a 55 gallon tank. 2 of them have paired off. She wants them to breed but is scared the rest of the fish in the tank will eat the fry. What sized tank could she move those angels into? She could get an established 10 gallon tank from her friend. Could they be moved into there to breed. I told her it may work for the breeding but what happens when the fry hatch? Would she be better off keeping them in the big tank. Maybe some fry will survive.
