A few weeks before I lost my male black molly.Now,the female black molly aggresives against other fish like gold fish and guppy.What should I do now?
Should I buy a new male black molly for her?

What is your tank setup? I have never had my mollies become aggressive towards any fish. Maybe it wants to be alone and needs a few extra hiding places.

It is odd for female mollies to become agressive. It does seem like she doesn't have enough space. Also, why do you have goldfish in with tropical fish?
