I dont know what this is?

I came home today to see this on my LT Tang. He has a spot on one side next to his head, and another similar spot on the other side on his stomach.

I can't really see much of anything except for the last pic.

Can you take some pics with whites on and post?

It's possible the fish scraped a rock or something. Again really hard to see much in pics.

Agree looks like it could be a coral sting but the blues need to go for better pics

Do you ever see any aggresion between this fish and the sailfin?

No. I have had both of them for 3 months. They were together at the LFS and have always been ok with each other. They even hide under the same rock together if they get spooked.

This may sound crazy, but that kinda looks like a bite mark from a blenny. Do you have one?

I do. I have a starry. He is kinda the ruler of the algae clip.

i had an achilles tang that came in super clean and after being in mt QT developed same kinda mark on lower bottom side. i figured it was scrape wound and let it ride. it took atleast a month for it to disappear. but it did go away on its own. i didnt treat for it. Although i had CP in the QT as ich treatment.
Only other tank mate was a purple tang but i have separators so they were in 2 different sections.

Has he ever shown aggression? Is he big enough to leave a mark that size? If not, then yeah, looks like an injury "not otherwise specified" lol.

He is big. He is as long as the LT. I have seen him chase the coral beauty from the clip but never the tangs.

I strongly suspect that DrStardust is correct ... that looks like a blenny bite, and starrys can see tangs as competition.
