Upside down fish

[amcgee2842]

Bought a few peacocks from fish gallery one being a ruby red. I notice when I introduced him the sunshine peacock had an issue with him but it was chasing around not hitting. So I thought he was just showing who was boss so I let them work it out overnight. This morning I could tell the ruby Red was stress but was perfectly fine with a few frayed fins but swimming normal but the sunshine was still chasing. So before I left for the day I netted the sunshine and put him in a bredder box. Came home after 8 hours to see the ruby red upside down and on the bottom and fins severely freyed I thought he was dead but he was still alive. I removed him and put in hospital tank. Not sure which fish got to him maybe the red zebra. my question is are the internal organs so badly damaged that they cant keep him right side up? What's the best way to put him out of his misory? Or is there any chance of survival?

It might be swim bladder. Sorry to hear that.
I think the most humane way is to wait. If he passed he passed, but there is a chance he can recover.
