Molies
I have platys and mollies too, and my goldust mollies occasionally chase each other around, but no damage is done-they usually get along fine. What gender are the mollies? It could be males fighting over a female-or in my case, my females chased each other! The lfs guy recommended adding a male to occupy the time lol but i never tried it. I wouldnt be adding any fish i there is ich in the tank-if some fish are showing signs and now ur molly is rubbing and "flashing" then it probably has ich too-which would account for its less active behaviour. theres a whole thread about ich in the general freshwater forum, have you heard of using high temps/and salt? I was just wondering because i used a commercial brand (nox-ich) i think, and it killed my neon tetras!(make sure u only use half the recommende dosage!!!!) theyre scaless and fragile when it comes to ich medications. Also on the commercial ich med it said to treat for 3 days, but u should actually treat for much longer because of the ich parasite's life cycle......just read the thread for details
I hope ur tank pulls thru!
