What is this on my tang?

This spot appeared today on the side of my tang. It was not there 6 hours ago. It looks like a burn on the surface of the skin and it does not appear to be affecting eating or swimming. I did just get a new carpet anemone and am thinking this could be where he came in contact with the anemone?

Any thoughts? He has been healthy and none of the other fish have any spots. It also looks like it's the shape of a kiss or bite mark.

Thanks.

Looks like a string of some sort for sure

It looks like a bite mark or abrasion of some sort. I would keep watch and see if it heals up on its own.

Ok thank you, I will keep an eye on it.
