i have 2 convicts breeding in a 55 with some other fish. i remove the fry and have 3 grow out tanks for them, a 10, 20, and a 55. im thinking of seperating the parents after the next spawn, there'll be around 500 fry(all together from 3 spawns). is the 10, 20, and 55 enough room to grow them out to a good feeder size?
