I havent got to the disease and treatment board yet to see if you posted there, but make sure you post this there. Forgive me if you already did. From what I read it may be HLLE . I'm not very experienced at this one, but Beth and Terry B on the other board are. You will need to tell them if you QT'd because its a new fish or you saw other sypmtons and then added because of. Again forgive me if you have already posted there.
