My purple tang caught a case....I put it in a timeout tank, by itself. I fed it a varied diet, added some selcon to it's food, and it healed on it's own.
well I had a few fish die from the power outtage in dec. Haven't really added much since then. I only have a lyretail anthias and a watchman goby in a 75g with the sohal. I'm pretty sure I can get him to eat whatever I want without much competition!
i have a hippo that had it bad when i got him soak your food n the selcon and also if you have any power heads in the tank get a ground probe any stray electricity in the tank keeps the hlle going by adding stress to the fish i did the selcon and a ground probe and he cleared up fine no sign of it at all now
