Yeah im starting to thinks that's the case. My other catfish, a pictus has the exact symptoms. Both catfish at this point have lost there whiskers and have just buds at the base, plus cloudy eye and torn up fins. I've lost three fish
but everyone that has survived is looking better. I'm going to cut the para guard dose in half to help out the catfish.. Also considering adding some triple sulfa, ive read it can be mixed with para gurad and help out with some of the secondary infections and make the paragurad less bothersome to sensitive fish. Good Idea? Also is triple sulfa filter safe?? Thanks
