Hi, we got a tank yesterday with fish in 2nd hand, we have a black male molly and a while female, the white female looks more than ready to drop but she is constantly chasing the male...is this normal behaviour? I thought the 2-1 ratio was so the m didn't harrass the f?! it seems to be the other way round. They are quite large mollies and i was going to get another f but i don't think i would find a lfs that sells them as big! Should i still get another female?
