The Desjardini Sailfin Tang, also known as the Indian
Ocean Sailfin Tang, Desjardin's Sailfin Tang, or Red Sea Sailfin Tang, is dark
to very light gray in color with light freckles on the nose and yellow freckles
on the abdomen. The body has several, varying sized vertical yellow stripes
with intricate markings between the stripes at the face. It has a blue tail
with white freckles. Its appearance can practically double in size at will by
raising or lowering its sizable dorsal and anal fins.

A 180 gallon or larger aquarium is necessary to provide
plenty of swimming room. It is aggressive towards its own species and
conspecifics at times, but peaceful towards other fish, so keep only one except
in a very large tank. It eats filamentous algae.

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. This will strengthen their immune system, reduce
aggression and improve their overall health. Offer dried seaweed tied to a rock
or use a veggie clip, and feed at least 3 times per week.
