All my fish are good to go! But I have noticed on one of my fish about a week before I left had a spot on him, so I treated it for fungus. I treated before I left and now that I am back it looks the same! When I looked at it really close, it looked like either the scales were ripped off and not grown back yet or they are discolored. Can melafix fix it? Other than that everything is good. No strange activity or anything...
