I almost didn't do this as I have been here a lot. But, after dispatching a bent/emaciated old bloodfin it was a good assumption it had developed one of the pathogens that cause wasting disease. I just did more research on this and I am almost as confused as ever. These white clouds<a href="http://s1049.photobucket.com/user/lv2crp/media/009_zpsawy2ggs5.jpg.html

and one other are still feeding but are not vigorous fish. My reading has me looking for visible parasites as well as understanding there may be none. As well, I can't help but wonder if the neon tetra disease may be the problem. I do not over feed, and the other fish are fine. These are sick, but how much so? This has been going on for possibly 2 weeks, the fish like this. I don't want to use my QT as it has new fish, supposedly healthy, in it now. One site says to get such a fish wasting away out long before it dies. I can do that. If I treat with fenbendazole and this isn't the problem am I damaging my other fish. It seems I am rehashing a problem I just brought up I know.
