Fish With Swim Bladder Problem

[SimShadow]

Hey all,
 
I have a Silver Dollar that has been struggling with what I assume to be swim bladder disease. He spends his time frantically swimming towards the surface just to stay buoyant. 
 
It's been over a month since he started doing it. I have tried epsom salts, feeding green peas and fasting but nothing has worked. I figure it must be an internal injury or infection.
 
Should I euthanise the fish, or let him be? Despite the issue, he is eating normally, but I don't know whether he will ever improve.
 
Opinions are much appreciated.

I know fish can survive for a long time with swim bladder problems. I had a goldfish that lived upside down for a long time with no problems.  
 
I think as long as he doesn't seem in pain and eats fine you should let him be.
