Looks like ammonia poisoning but you have no ammonia possibly the mild nitrate?

Absalutely no ammonia for years! The water comes out of the tap with 40 nitrate in it. (always has)

Nitrate needs to be a LOT higher before it actually hurts most fish. I think your fish was just weak or something... if you lose another fish, THEN you might have a problem.

Its bacterial bless him R.I.P.

It does look bacterial, possibly BHS.

If the problems continue (==another fish gets infected), Maracyn2 or a similar antibiotic may be a good idea.
