The maroon clownfish, Premnas biaculeatus, is a species of clownfish that is found in the Indo-Pacific from western Indonesia to Taiwan and the Great Barrier Reef.[2] They can grow up to be about 17 cm (6. 7 in),[3] and as they grow, they become more aggressive towards other clownfish. It is also known as the spine-cheeked clownfish. It is the only member of the genus Premnas,[3] although it has been suggested that the taxon epigrammata from Sumatra should be recognized as a distinct species, Premnas epigrammata (Fowler, 1904).[4]

The stripes across the body are normally white, but they are yellow in the taxon epigrammata. The female is usually larger than the male.[3] The female is also and dark red or maroon, while the male smaller and a bright red.

In the wild, the fish's only host is the bubbletip anemone, or entacmaea quadricolor.[3] The fish's natural diet includes algae and zooplankton.[3]

In captivity[edit]

Many hobbyists believe that a 30-gallon tank is best for one fish or 60 gallons for a pair.[citation needed] In the wild, it is strictly associated with the sea anemone Entacmaea quadricolor,[2] and thus many hobbyists provide this species in addition to the fish. The maroon clownfish likes frozen shrimp and herbivore preparations.[citation needed]

Many hobbyists do not catch the fish using a net.[citation needed] The spines may get entangled in the net, which can injure the fish. Instead, hobbyists tend to use a cup.[citation needed]

The maroon clownfish is one of the larger, more aggressive members of the clown family. Consequently, they are typically housed singly, the only exception being a mated pair.[citation needed] To avoid aggression, maroon clownfish are not normally mixed with any other type of clownfish, and the rock work is rearranged periodically.[citation needed] Also, they are often the last fish added to a tank.[citation needed] They are human-responsive to the point of trying to "intimidate" people with whom they are not familiar.[citation needed]

The fish has successfully bred in a home aquarium.[3]
