I have a 60 gallon tank with about 10 goldfish. It is well filtered and clean. Recently I added a pleco who died within a few days. After that all the goldfish got sick. They seem fine but then suddenly their mouth and gills stick wide open and they start vibrating wildly like they are having seizures then fall to the bottom dead. I tried treating for common funguses and changing some of the water but the slightest change seems to set more of them off so I stopped doing anything. I cant find anything on this so anyone who knows how to help them please tell me.
What causes fatal seizures in fish?
