Guppies And Mollies

[This Old Spouse]

I have a 55g where I had one female and two male mollies (not by design). The males were harassing the female so much that I just put her in with my 2 female and one male guppy. Now the molly is chasing the guppies all over. Does she need her own tank until I can get some more females? Thanks ...

Mollies are aggressive and will almost always bother guppies.

Mollies and guppies generally get along well together though it's best to keep them in larger numbers.
Some mollies can be bullies - I had one that even attacked angelfish when I first moved them into her tank!
