I did 3 salt baths yesterday, he seemed to enjoy them or maybe it was the break from watching over his minions. I know one spot on top is a damaged scale but even after the baths there are no changes to the spots. I have aquarium salt in his tank and do weekly 25% changes, adding 25% salt back to the tank and a dosage of API's Bettafix. I also use a turkey baster to remove any food after about 5 minutes to prevent any decaying food issues (course the ghost shrimp and corys do a good job there too.) He's active, curious and shows no physical signs other than those spots. Here's the best picture I could take (the spot on his side is a spot on the tank,) he really hates the light off of the camera.
