Those are weird. Wondering if these are Genus Paravortex flatworms? (That's my wild guess)

That blue tang looks decent, in my opinion. I don't see anything too concerning. I would just call those bruises or scrapes and monitor while treating for ich. Could be a little HLLE, which is common in tangs, and can sometimes be corrected.

I'll admit I've never seen the word Paravortex. It's not the same as black ich (worms), is it? The fish doesn't seem to have black ich.
