I currently have an Oranda dying from the illustrious hole in the head disease. Does anyone know how this disease occurs? I read on a website that poor water quality and a bad diet are to blame. I do 1/4 tank water tank changes once every week and i give him a varied diet. I don't think this is the problem with my fish.
This disease is awful for those who know what its like. It looks like something is eating away the top of the fish's head. I also read that the disease primarily only affects Cichlids, Oscars and tropical fish; but an Oranda? Any info would be much appreciated. Also, are goldfish with Wens at a greater risk? Thanks so much
