I hate Platy's! The one my wife picked out gave my P. Taenaitus Dropsy. I hope the Jungle Clear works. I am now treating the whole tank just in case. Wish me luck.
Why would you have livebearers in with cichlids? It's not the platy's fault, I'd blame the fish store for selling a sick fish. How long did you quarantine?It wasn't new. But every fish illness I have had has started with live bearers qnd end up killing off a cichlid. Never had any problems with fish illness until I brought home these darn Platys.
