I just read this thread http://www.monsterfishkeepers.com/forums/showthread.php?t=162813 . ATM I am treating with Organi-Cure. It says it effectively treats Protozoan Parasites. Are Protozoan Parasites the problem of my dats heavy breathing? His gills seems tobe moving very fast so I scooped him out and he is in the hospital tank. If Protozoan Parasites is not what I am curing then I will go buy coppersafe tomorrow.
