Blue Tang, Blue Tang Surgeonfish Description: Atlantic Blue Tangs come in shades of light to dark blue depending on diet, health, stress, and environment. They are somewhat of a challenge to keep as they do not easily adjust to captivity. Because of this, smaller specimens are recommended.
The blue tang goes by several aliases, including blue barber, blue doctor, blue tang surgeonfish, yellow barber and yellow doctorfish. The terms "barber," "tang" and "doctor" refer to the extremely sharp spines on each side of the fish’s tail, which are said to resemble surgeon’s scalpels.
The bluespine unicornfish or short-nose unicornfish (Naso unicornis) is a tang from the Indo-Pacific. It occasionally makes its way into the aquarium trade. It grows to a size of 70 cm in length. It is called kala in Hawaiian, and dawa in New Caledonia. References. Froese, Rainer and Pauly, Daniel, eds. (2008). "Naso unicornis" in FishBase. December 2008 version.
In this genus, you will find aquarium favorites like the blue eye tang (Ctenochaetus binotatus), the chevron tang (C. hawaiiensis), the flame fin tang (C. tominiensis), the spotted yellow eye tang (C. truncates), the striped bristletooth tang (C. striatus), and the yellow eye Kole tang (C. strigosus).
The orangespine unicornfish has a continuous, unnotched dorsal fin with VI spines and 27-30 soft rays. The anal fin is long, with II spines and 28-30 soft rays. The caudal fin is lunate; adult males develop a long filament from the tip of each lobe. The caudal peduncle bears two forward-directed knife-like plates.
The Sailfin Tang fishes help in keeping the corals healthy by preventing overgrowth of algae by feeding on them. The distinctive feature of the Sailfin Tang is that they have different body marking that keeps on changing from juvenile stage till adult stage. At an early stage, the Sailfin Tang feature medium brown to yellow colored body with bright yellow and black stripes. Whereas, the adult body shows a brownish-olive color with both striped and dot patterns on it.
