Description
The Lieutenant Surgeonfish is a large, oval-bodied surgeonfish known for its pale body and two distinct dark bands behind the eye, which can appear as a single 'mask'. It features striking blue trim on its fins and a prominent blue ring around its caudal spine. This species requires a spacious aquarium due to its size and active swimming habits.
