If it wasn't in the wrong place, I'd have said those lesions look like Head & Lateral Line Erosion - Possibly @HotRocks, @Big G, @melypr1985 or @Humblefish will have seen - and treated - something similar.

I believe that is HLLE: https://www.reef2reef.com/threads/hlle-head-lateral-line-erosion.259916/

Just very odd for it to be near the belly like that.
