guppies.. they are rather plentiful, or perhaps convicts.. although i've never bred convicts, but i've had great successes breeding guppies. if you breed enough pairs in the same tank, inbreeding is less likely, and the more fry, the less that get eaten by the others.![]()
I second that. Get three guppy females and one male. Provide some hiding places for the fry.. Plants, real or plastic. You should be hip deep in guppy fry about once every 15 days or so.
