hi all so i got 2 platys 1 male 1 female my friend asked me if i would try to breed him some baby platys for his 20G he told me he wonted a cross breed of a red wag tail platy and a sun burst platy so i think it should be a red platy with a larger tail but i have a problem i got the 2 fish and bam they swim a way from each other the male is making a big pile of rocks and wont let anyone get near it is this normal? the female is hiding but she looks a little big could she already have baby's in side her? why wont they get to geather? thanks for your help
