I have 4 platys (1 male 3 females) and really want them to breed. they are kept in a 15 gal with some guppies and zebra danios with a pH of 7.5 and a temp of 25-26 degrees celsius. The females are about 5cm big. The male doesn't even look as if hes interested in them. Even my mollies have bred and the platys haven't. Is there something wrong?
