Rigel has been pretty lethargic lately, for a few months now. He was never very active and I figured he was just getting old.

A few days ago, I noticed his left gill had a whiteish growth underneath. It is not fluffy like fungus, looks like a pimple.

I put him in my 5gal heated QT tank today, with some Kanacyn anti-biotic and Aquarisol (in case it's a parasite-like infection)

I am going to keep a close eye on him - he is one of my oldest and I really am attached to him.

Ideas / diagnosis help are welcome!
