Ctenochaetus strigosus is the most common bristletooth. Common names include Kole's Tang, Yelloweye Bristletooth, Yelloweye Surgeonfish. Any tang in that genus can be called a bristletooth tho.
You should also check under Tomani Tang. It is a bristletooth tang, relaetd very closely to the Kole Tang, but with orange fins.
I have been seeing a lot of "pale" "albino" Kole's in lfs lately, so it might be that.
