I have a breeding pair of convicts that I moved to their own 55 gal tank so they can breed and have all of the fry with them so I wont have to have a seperate tank for the fry and they wont cause harm to anyone who wants a snack. lol. But now it seems they have stoped breeding because there is no enemy? I'm not sure if this is why maybe they have too many babies? Should I add any fish with them, if so What should I add? I dont want to overload the tank and I will probably sell some of my babies soon. Any ideas would be great.
