A girl at my college asked me for help with her crowntail male and I happily obliged. She gave me the run around for quite some time until finally her roommates let me to see him. At this point his was conditions were visibly bad, with little room to swim and he appeared dead until I took him out and put him in a cup of clean water to take home.
He is in about an inch of medicated water to heal his severe fin rot/biting and what I believe is swim bladder disease (Epsom salt and a few drops if bettafix). He hasn't eaten for almost a week according to her and her roommates and won't accept food. He lays on the bottom half slumped over and can barely reach the top for air.
He swims decent enough, but his tail is short and weak from biting and/or fin rot and he is malnourished. He is very willing to stay alive, but sadly had been living on minimum food and in horrible unclean water for months.
I've never had such a severe case before. He seems to be more active in his new clean water but otherwise I don't know, I just got him home. Suggestions?
