A friend of mine left her Parrot Cichlid with her mother who lost power in the winter storms of Texas. He was without heat and oxygen for about 24 hours. The mom took the fish to her daughter in a bucket where they put a heater in to warm him up. He's starting to lose color and he's laying on his side. I know a little bit about fish from experience and research, but this is something I don't know much about. My fish have never been without heat and oxygen for so long. I suggested getting a bigger tank, first of all, for the time being. They apparently can't put his normal tank in their apartment or they'll get in trouble. I also suggested getting a filter or an air pump with an air stone to provide him with oxygen. I've run out of ideas that could help him and any feedback would be appreciated! The picture attached is one she sent me this morning when she thought he was dead.
