Sorry, originally posted in wrong thread. New to forums also.... I have 2 male guppies, 2 male platys and 3 neons in a 20 gal tank. The problem is the 2 male guppies constantly harrass the platys. I also have noticed the platys chasing each other. Is this normal or a male thing? I purposely didn't get any females, because I didn't want a tank full of guppies. Thanks!!
