Thank you everyone for your response, even though it took a while for the replies. My loach turned out o.k. the spots went away. My syndontis cat was the worst of the crew, although, I had a lot of trouble diagnosing what he had at first I thought it was ich so I treated them with a regular dose of malachite green and some other ingredient, the loach cleared up quickly. The catfish seemed worse and fuzzy, so I did a water change and treated the tank for fungus and he is clearing up, but still has some problem areas. He gave the stuff to some other community fish, they all got treated the same but the others weren't so lucky. That is really frustrating. Thank you again,
