I have been wanting to add some male guppies to my tank. I have two female balloon belly mollies and 4 neon tetras. Will there be any problems with the guppies trying to breed with the mollies? Also will the male guppies fight? How many should I get to prevent aggression with each other? Would 3 be ok?
If the guppies aren't a good idea, does anyone have some small hardy fish suggestions?
