Betta Has Large Round Tummy?

[proton]

Hi All, I am now very very worried. I have a Betta and he has been ill now for a very long time. I have treated the tank with salts (for tropical fish) from the LFS. But he is very very poorly. Is is just sitting on the bottom and he has a very round tummy and seems to be batteling to swim. He can't even swim. Can anyone suggest what it could be? Could it be Dropsy?

Are his scales sticking out.
All you can do it try some epson salts baths to help draw the fluids out.
If the betta on its own in a tank you can add the epson salt to the tank.
Other types of salt don't do much when there bloated.

Could it be swimbladder disease?

Also, could I put him in a cup and give him some epsom salts for a couple of hours? Or is that not recommended?
