Acanthurus tennentii
The Vampire Tang (Acanthurus tennentii) is a bold and active surgeonfish named for the small “fang-like” markings near its mouth. Known for its striking grayish-blue body, yellow dorsal highlights, and dark facial band, this tang adds a unique presence to large reef aquariums. Despite its common name, it’s a peaceful grazer most of the time, though it can become territorial toward other tangs, especially those with similar body shapes.
A large, open swimming space is essential for this fast-moving species. The Vampire Tang thrives in tanks of 180 gallons or larger, with plenty of live rock for algae grazing and natural shelter. Maintaining excellent water quality and strong circulation is key. Provide nori sheets or algae-based pellets daily to satisfy its herbivorous diet and reduce aggression.
Due to their active nature and susceptibility to ich, quarantine and a UV sterilizer are strongly recommended.
