He seems to be acting normally and I did give him a quick epsom bath.
There are quite a few new items in his tank, But he responded by playing with the new moss ball and chillin in his rock cave. Background upset him for a couple hours, but he calmed down.
After a bit he did have quite a large BM for such a tiny fish and some of the bloating went down. He has been swimming all over the place and rolling on his moss ball.
He already has aquarium salt and the tank is heavily planted and cycled. I usually do 2-4 gallon water changes, but have cut back this month due to the cycling benefit.
Still waiting on a new bubble nest though :(
