hmm here's an update... the condition worsened and im probably guessing it's the pleco I have in the tank. Or does these look like something else rather than bite marks? Funny thing is all my 3 other rays are fine so i doubt it will be any water parameter problem causing burns. If it's another ray biting him or the pleco sucking on his disc, why are the other 3 in perfect shape?

It may just be one of those things that the pleco only sucks on his disc and not the others. I would definitely take the pleco out and see I that helps and if the disc improves.
