Last night I was looking at my tank (sounds like the opening to a very bad novel) and noticed that my Naso had a small white patch on his side. Over the course of 45 minutes, the patch spread, but the fish was behaving normally. I almost posted last night wondering what was up, but I figured maybe he got stung with an anenome. The white patch faded and left behind a hyperpigmented oval spot, maybe 1/2 x 1 cm.
This night, the same thing but on the other side, but this time I saw a circular line within the white patch, almost like something tried to latch on to him. I have a yellow tang and a hippo in there as well, but for the most part they all get along. It's about the right size for a bite from the yellow, but they've been in the same tank for 3 months now! (see attached photo)
Please tell me this isn't some horrible worm infestation or nasty parasite or creepy crustacean. If you are going to tell me one of the above, then please also tell me that there is an easy way to fix the mentioned problem. Thanks for the help!!!

BTW: 1. The first mark was noticed shortly after a water change.
2. Yes, I have gotten new SPS recently from several other members as well as from an LFS. In addition to hitchhiker crabs I have seen on the acro I picked up from the LFS, I recently noticed my first hitchhiker fish (from what I can see, it's turning emerald green).
3. Haven't heard any clicking sounds indicative of a mantis, all other shrimp and inverts in the tank are okay.
