Chaetodon biaculeatus Bloch, 1790
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. They can grow up to be about 17 centimetres (6.7 in), 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, although it has been suggested that the taxon epigrammata from Sumatra should be recognized as a distinct species, Premnas epigrammata (Fowler, 1904).
The stripes across the body are normally white, but they are yellow in the taxon epigrammata. The female is usually larger than the male. The female is also and dark red or maroon, while the male smaller and a bright red.
Maroon clownfish are maroon in colour. Females of this species are larger then males. Females can grow up to 17 centimetres (6.7 in).

Many hobbyists believe that a 115 litres (30 US gal) tank is best for one fish or 230 litres (61 US gal) gallons for a pair. In the wild, it is strictly associated with the sea anemone Entacmaea quadricolor, and thus many hobbyists provide this species in addition to the fish. The maroon clownfish likes frozen shrimp and herbivore preparations.
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. To avoid aggression, maroon clownfish are not normally mixed with any other type of clownfish, and the rock work is rearranged periodically. Also, they are often the last fish added to a tank. They are human-responsive to the point of trying to "intimidate" people with whom they are not familiar.
The fish has successfully bred in a home aquarium.
