The blue tang goes by several different names, including blue barber, blue doctor, blue tang surgeonfish, yellow barber, and yellow doctorfish. Most of these names refer to the extremely sharp spines on the sides of the fish’s tail, which resemble surgeon’s scalpels and are used for self-defense when threatened.
