HELP! my fish jumped out!!!!!

Well my old blue dwarf gourami that has been through EVERYTHING bad that could happened to a tank just tried suicide! He seemed a bit constipated lately so i was moving him to my hospital tank for treatment. i had him in a tall tupperware bowl with original tank water and was drip aclimating him with a tube.

We left to go pick up food and came back to him on the carpet! He was nearly totally dried out, his fins and scales were crispy and his color was dark blue and he was not moving. I grabbed him up, tossed him into the water and was cupping him in my hand and moving him around trying to get water into his little dried up gills when he started breathing and as I plucked the carpet lint of of him, the little bugger began to swim on his own
He seems to be able to swim OK and is able to keep himself upright on the bottom and swim up to the surface to gulp air.
So now what should I do? his scales seem pale/dark in spots and I'm sure that his slime coat is damaged. Should I keep him in shallow water so the trip to the surface is shorter. Should I add stress coat? Melafix? I don't want to stress him any further . I can't believe he is still alive!

When i say dried out, I mean crispy like a potato chip! He was so dried out that he had completely changed color, his fins were hard and stiff along with the entire side of his body that was face up. i studied his body for at least 1/2 a minute and was about ready to put him in the trash when I decided to try to 'reconstitute' him. He was probably there for at least 20 minutes.

I know that I need to just wait and see if he wil survive but I have the need to feel like I am doingsomething to help him. Is there anything else I should add like maybe salt or something?
