What tang is this?

[ryan_tplrwint]

I was given a tang off a friend who was shutting down his tank. Unfortunately I can’t find the breed of tang anywhere and my friend doesn’t know it either. Can anybody tell me?

also, please ignore the algae. I’m running the tank without a protein skimmer but I’m getting one this weekend and going to be using NOPOX to help remove it.

Ctenochaetus sp for sure. I think it's C. striatus.
