Tank compatibility[edit | edit source]

In smaller tanks will be aggressive towards other Tangs of the same species or similar. In larger it tanks should be ok in groups, since travels in large shoals in the wild.

Diet[edit | edit source]

A grazer in the wild, proper nutrition is crucial to the success of keeping this fish. These fish are often shipped in with internal Parasites or compromised Gut Bacteria, which is usually fatal lacking proper treatment. As soon as these ailments are treated, they should be offered copious amounts of Nori, Seaweeds, and small meaty foods for nutrition. It is best not to feed Tangs terrestrial greens, as these are practically void of useful nutrition and can contain harmful acids.

Behavior[edit | edit source]

One of the more peaceful Surgeons, it has very small "tangs", and will rarely act aggressively towards other fish. Like all Tangs, caution should be taken when housing it with related or similar looking species. Like its cousins, it is a very active swimmer, and should be housed in a tank no less than 75 Gallons (284 Liters).

Environment Specifics[edit | edit source]

A spacious, mature, and stable tank with lots of algae growth will suit it well. Avoid housing it with aggressive tank mates, especially aggressive Tangs. This fish doesn't have the means to defend itself like other Tangs. Given a suitably sized system (over 125 Gallons/473 Liters), this fish can be housed in groups relatively peacefully.

Identification[edit | edit source]

Identification is rather straightforward, with a compressed and tall white body that has several black bands. The Zebra Tang, Acanthurus polyzona, looks somewhat similar, although has a much denser banding.
