Terry thanks so much. That does help, but identification is not my forte. Neither is photography. I've tried taking pictures of the fish, but they all turn out either very dark or very blurry with him moving around all over the place. I've only got an old 2.1mp elph. I understand what you're saying about the dips, but is that more stressful on the fish to be fetching him in and out of the tank numerous times only to be put in less than hospitipal conditions with a moderately high concentration of formalin? Right now he is swimming merrily in a 50gallon QT tank in my garage with the recommended dosage on the bottle. I figure this way I'll leave him in there longer, but at a lower concentration. In my mind this was put the fish through less stress. Wouldn't you agree? Maybe at best what I can do is at some point take him out of the QT tank into a dip bath to then finally be placed back into the main tank? I'm still not really sure if it's brooklynella or not though. It started out looking more like abrasions on him, the on his orange sections it kinda of darkened up a bit. On his white areas the scales have kind of bubbled up, but it's staying white. Does that help at all in diagnosing?
