Hey, I recently got a 29 gal. tank. After cycling it without fish for a week (enough time?), I bought 2 black mollies (M and F). The Female is relatively large (almost 3 inches) and bullied the male (2.5 in.). I then bought 2 more females, a dalmatian at 3 inches and another black molly at 2 inches. There is no aggression among the females. The only problem is the original 2, where the large female attacks the male whenever he swims near. I want to breed them, but I don't think it's going to happen if this continues. Should I remove the Female? Or get a different male? If you need more info, my tank is mapped out on my profile.
