A week ago I lost a percula clown. I never figured out why but he developed rapid breathing, swimming in the direct current of the power head. Then started getting white specks on the top half of his body but to me it didn't look like ich. The next day he was dead. Today my other much smaller percula is gone, (Im pretty confident he's dead) He had the same symptoms except he wasn't swimming in the current, he was hiding under a cave. He also has a white string that would come out of his anus. It would go away and then another would come out. He had the same white spots up on his top fin area. I have a beautiful Yellow Tang and a 6 line wrasse in there now that look great, but Im afraid that they may get whatever killed the other two. Or is it something that may have been associated with the clowns only? It took about 3 or 4 days for the second clown to develop what the first one had after he died. I don't know what to do. I really don't want to loose them too.
