Well, I've tried everything to try to decrease aggression between my two balloon belly molly males, and my last option is to go get some more to hopefully spread out the aggression. I thought about seeing if my LFS would take back the males and just getting a bunch of females, especially since I am raising a single female molly fry that I dare not put in the tank in its current state. My question is- if I were to get females instead, would the male dwarf platies try to breed with them? I have three of these, and they're very happy and nice and want to keep them. I know they're all livebearers, but I thought it might be possible that the platies would leave the mollies alone, since they are like 1/5 of the size, but I didn't know. I really don't want babies of any kind. Suggestions? Thanks!
