Darting Platy! Aggressive Molly! Help!

[mr.waffles1842]

Hi guys! I have 6 fish in my 20 gallon tank; 2 corys, 1 silver molly, 1 black molly, and 2 sunset fire platys. I have a male platy who is darting around at a rapid pace! I know when fish are about to die of old age they dart around wildly, but ive had this guy since he was born 3 months ago! Any advice would be appreciated. Also, my lack molly is chasing all of my fish around. PLEASE help!

could be that hes just scared of the mollies... i know they can be bullies... If not, is there anything visibly wrong with them? Loose scales, scaleless parts, white spots, etc.?

Water are your water parameters?

And Mollies will behave like that, they are establishing territory's.

I got your email. I think the platy looks fine. Keep that black molly in that net!
