I have a mating pair of Black Convicts with 2 Green Terrors and 2 Jack's. By far the meanest are the Convicts, especially when breeding, followed by the GT, then the Jack's. The Convicts are prolific breeders and I'm not sure why they don't have long ears and a bunny tail... :evil_lol: Momma likes to eat the fry for a snack if the other fish try to invade their area, then the male takes over and keeps momma out of the breeding area, but by then the fry's are pretty much all gone. I'm guessing the male plays the bigger role in raising the fry. They are really good at fending off visitors and I kinda feel sorry for the others. I don't try to save the fry mainly because I wouldn't want any more Convicts in the tank. If it's a tank of just Convicts, the fry should have a much better survival rate.
