Description
The Bluespine Unicornfish is a large, distinctive marine fish known for the prominent horn-like projection on its forehead and two bright blue spines on each side of its caudal peduncle. These herbivorous tangs are active swimmers that require very large aquariums with ample rockwork for grazing and hiding. They are generally peaceful with dissimilar tankmates but can be aggressive towards other tangs, especially those of similar shape or size.
