Overview
The clown tang is a demanding surgeonfish for a very large reef tank. Only experienced keepers should try it.
Did you know
Clown tangs ship and acclimate poorly, so a healthy long-term specimen is a real sign of a well-run tank.
Caring for the clown tang
Give a clown tang at least 238 gal (900 L), with strong flow, high oxygen and long swimming runs. Adults are constantly on the move.
Keep the water pristine at 75 to 81°F (24 to 27°C) and a pH of 8.1 to 8.4. This tang is prone to ich, and to stress if crowded.
Offer constant grazing food such as nori, spirulina and macroalgae, and feed it heavily. It is reef safe with corals, but it may nip large-polyp stony corals if underfed.
The clown tang is one of the more aggressive members of its genus and bullies most tank mates. It is highly aggressive to similar fish, so keep it as the only tang. Add it to the tank last.
Good to know
Acanthurus lineatus carries a notably large tail blade that is associated with venom. Its blue and orange stripes are among the boldest of any surgeonfish.
In the wild
Clown tangs range across the Indo-Pacific, from East Africa to the central Pacific. They live on the shallowest, most turbulent part of the reef crest, where they fiercely defend a grazing territory.
