My flasher wrasse was on his side for the whole drip process. Put him in the tank after 2 hours. He started doing barrel rolls and then ended up upside down. His gills were still moving a little as if he was gasping for fresh water.
I decided to let him go out humanely instead of the toilet bowl of despair. Grabbed him with my hand an put him in a breeder box.
The next morning I came down and he was swimming around the box as if nothing ever happened.
Moral of the story, don't think they are dead until you know for sure.
