Help me cory floating

[Rainbow_fish]

I think it has swim bladder disease. I have no other tank to put it in so its staying in its tank for now. I was reading an article on this and it said to feed peas or fast for a few days. Any ideas if these meathods work. Please help me and tell me if he will be ok.

Treatment: Raise the temperature, add appropriate medication for swim bladder. Note this is a disease that is rarely curable.
