Is this HLLE?

It has had these markings fot quite a while. Never thought much about them. Looks like slightly pitting.

It is acting normal and is always eating.

I tried to take a picture while it was sleeping after the lights went off.

This is light facial erosion associated with HLLE and causes pits and flesh missing mainly in tangs, angels and some rabbitfish. It is often caused by poor water quality, high use of carbon, poor water quality (elevated nitrate and ammonia) and inadequate/poor diet. It is not life threating in any way but offers secondary infection in some cases.
Maintaining GOOD water quality and diet are often the fixes and with severe cases, some healing.
Some foods to feed tang are :
LRS herbivore diet
Formula 2 flake and frozen
TDO Pellets
small plankton
Hikari Marine cuisine
Ocean nutrition veggie diet
spirulina brine shrimp
mysis shrimp
Prime reef
Nori seaweed basted with garlic extract

Add selcon vitamins to foods occasionally

Yes - that’s a minor case of HLLE. It won’t cause any long term health issues, but does affect the fish’s “looks”.

Here is an article I wrote about it:
