Koi jumped out, what do I do?

[Atitagain]

I moved the two koi this morning, tank placement was 6” off floor so when they were spooked they went down. New placement has them eye level or slightly above and I guess one got spooked and went up and out of the tank on the floor. I’ve been in and out of the fishroom with lights out since I moved them. It has been about an hour I can say for sure he was still on the tank.

when I found him on the floor there was no movement so I scooped him up with a wet net and put him back in the tank. He started twitching and gasping. Some of his scales were off on the floor carpet. It’s been 10-ish minutes and he seems to be holding on.

what should I do? Salt, wait and see, a certain med, ???

Was gonna post a couple pics but can’t really see because of his natural coloration. So they just look like a fish floating on its side.

He’s turned upright and gasping getting stronger

I feel so horrible, the little guy. He has carpet fibers stuck to him. It is right at 6’ to rim of tank. And to top that it’s the neighbors fish I’m taking care of for the winter 😦☹️

I would let him stabilize in the tank.  Monitor for now.  He just went through some stress.  Be ready with a salt bath if he shows signs of infection.  I think throwing him in salt or introducing medication may stress him out further.

Koi are tough little fish. He'll likely bounce back. I wouldn't compound his stress with any unneeded changes in meds or water chemistry.

Wait and see, time in good water will make all the difference,  you are doing all you can. As said by others these are sturdy fish.

Carp are tough, agree with @Nuggets Beardabout a salt bath potentially for the damaged scales. Extra oxygen with an airstone. I know you keep the tank pristine but some extra water changes could help. Poor bubba, nothing you could have done this is such an individual fish thing.

What a sinking feeling when you find a jumper. I can relate. I recently lost one of my orange lemon tetras because I was messing around in the tank before sunup. That still makes me sick that I killed him. Hopefully yours recovers.

[Atitagain]

Thank you all very much,

he is seemingly pulling through, he is now swimming around and even pecking at the substrate. I will keep a close eye on him and do a couple extra water changes this week. 
ingot some decent pics now 1st is the side without much damage 2nd is damaged.

@Atitagain Doesn’t look too bad.  You should know more in the next 24-48 hours.  Just watch for now, like you’ve already planned.
