My stunted craigslist chocolate cichlid picked a fight with someone last week and got a huge chunk of his upper lip torn off. My course of action was to do some extra wc on the tank and keep an eye on things. Throughout the rest of the week, the damaged tissue sloughed off gradually and by Friday all the tissue on his upper lip had sloughed off. He also went from acting pretty normal to hiding over the weekend. I've pulled him out and have him in a 20g long hospital tank with a little aquarium salt, melafix, and pimafix. I'm not sure what to do at this point since I don't really know what to treat him for. The dying tissue simply gets white and falls off, but there is nothing fluffy growing on it, it just looks like the blood supply is cut off. Maybe I'm an idiot and missing some obvious infection. I just took these pictures and it's so much worse than it was this morning. Any advice is appreciated.
