Also wanted to add that he does not look like any of the "bloated" frog pictures I have seen. No real swelling on his top - just a rounded tummy a bit.

I put a little aquarium salt in there and am giving him some internal anti bacterial food (though he is not eating in his normal piggy way).

He can still dive to the bottom when I open the tank up, just cannot stay there. I would REALLY appreciate suggestions.
