the parents have amazing suction skills with their mouths, so a breeder net won't do... I tried it once and they killed they fry right through the net.... I think the only way to keep them from killing them is to move the pair to their own tank with no other fish. Usually, as juveniles, they will eat the first couple batches but will typically catch on to raising them at some point.... although some pairs may never.... the make your chance greater though, no other fish should be in the tank with them.
