Healed scratches or worse?

Not sure if this is a disease or something else, he’s had It for at least a few days, I don’t think this is an emergency but any help would be appreciated. Also there are spots on his dorsal and bottom fin but they’re not ich or velvet from what I can tell

Head and lateral line erosion (HLLE) and often due to poor water quality, poor diet and even heavy carbon use and stray voltage or heavy exposure to copper.
Assure ammonia-ph- nitrate not elevated and feed a good diet as these are herbivorous fish and cant get the fats and aminos needed from flakes and pellets alone.

Diet:
-Spirulina brine shrimp
- LRS Herbivore diet
- mysis shrimp
- small plankton
- Nori seaweed basted with garlic extract
- Hikari Marine cuisine
- Formula 2 flake and frozen
- Hikari veggie marine

Add selcon vitamins to the foods 2-3X per week and on alternating days, garlic extract for stamina and immunity health

The fish has head and lateral line erosion (HLLE). That is a chronic disfiguring issue, often a result of past carbon use. Resolving it is rare and usually requires moving the fish to a new tank that has had no history of it.
Those spots aren’t ich or other parasite…could be minor fin damage, what other fish are in with this tang?

I just moved him from a 15 gal temp home to the 120 gal display, I had to wait for a fish order to introduce the other tangs together which didn’t work out cause it was missing one tang, didn’t want the sailfin in the small tank any longer so I moved him in, now has a two spot bristletooth tang, carpenter wrasse, royal gramma, coral beauty, fire fish and a clownfish
