Acanthurus tennenti

The Tennenti Surgeonfish, also known as the Vampire Tang or Lieutenant Tang (Acanthurus tennentii), is a striking marine fish renowned for its distinctive appearance and active behavior. This species is native to the coral reefs and coastal waters of the Indian Ocean, particularly around Sri Lanka and the Maldives.

Adult Tennenti Surgeonfish can grow up to 10 inches in length. They exhibit a sleek, elongated body with a pale blue to gray coloration. One of their most notable features is the pair of sharp, scalpel-like spines located near the base of their tail, which they use for defense. The name "Lieutenant" comes from the two yellow or white lines that run along their sides, resembling the insignia of a military lieutenant.

In the wild, Tennenti Surgeonfish are often found grazing on algae, playing a crucial role in maintaining the health of coral reefs by preventing algal overgrowth. They are highly active swimmers, often seen darting through the water in search of food.

In captivity, Tennenti Surgeonfish require a large aquarium with plenty of swimming space and live rock to graze on. They thrive in well-maintained tanks with stable water conditions and are generally peaceful but can be territorial, especially towards other surgeonfish. Their diet in captivity should consist of a variety of marine-based algae and seaweed, supplemented with high-quality pellets and flakes.

With their elegant appearance and dynamic presence, Tennenti Surgeonfish are a popular choice for experienced marine aquarists seeking to add a touch of vibrancy and ecological balance to their reef tanks.

Use caution when housing with other Tangs or Surgeonfish. Similar shaped Tangs can be very aggressive towards each other. Although Tangs will eat meaty foods along with the other fish in the aquarium, it is important that they are offered plenty of marine based seaweed and algae.

It is well known that tangs have a penchant for Marine Ich and other diseases due to their lack of slime coating. We highly encourage quarantining all fish, but especially Surgeon Fish. We do our best to quarantine all fish at Reef Chasers but there can be absolutely no guarantees.
