i have read about the disease on my tang and know that its something that needs to be addressed right now. i dont have a qt tank large enough for the tang to stay in for a while so i was wondering if i could rid the disease by buying a certain fish (i forgot what it was called) that picks parasites off your fish. i think it was a 6 line wrasse. i know the disease is internal but i know for a fact that it has just started this morning.
