Just wondering, i've had a nasty outbreak of ich in my tank that just refuses to go away. I've treated with copper, but my maroon clownfish still has these large white cysts on his left side of his face which he's had for awhile, it looked like a bite mark for awhile but i'm thinking now its just really thriving ich cysts on his face. I've dipped him in a quick cure bath a few times and i was gonna take him to a QT
, but i was wondering how long the ich can survive in the tank without something to eat, and is it necessary to place copper in while the fish are gone from the tank. It would be empty for however long it takes for the ich to die off.
