I did try to put some guppies in with my breeder tank but they didnt produce. I also heard that swordtails will not breed if they were in a tank with other types of fish, besides mollies. I think that if your breeding for feeders, the mollies and swords would be a better option because you will get around the same output but they will be larger.
how long does it take for convict eggs to hatch, and how old do Convicts have to be to lay eggs?
