Just a tip, a fish youtuber I watch described and filmed a filmed a little him reviving a fish that had jumped out of the tank, and had been out of the water for a while, dried out, not showing signs of breathing. He held it facing into the filter output so water was flowing over its gills, and held it there for 10-15 minutes as the fish slowly revived, and it survived.
So even if it seems hopeless, it's at least worth a try to use this 'fish CPR' should this happen to anyone else!
