This species of this monotypic genus differs from the Amphiprion spp. in having a spine on the cheek and smaller scales than the other anemonefishes (Michael, 2008). The Maroon Clownfish (Premnas biaculeatus) has a maroon body with 3 vertical white stripes or lines on its body. There is also a gold stripe Maroon Clownfish variety that comes from Sumatra and the gold stripe is usually a little more expensive. This fish may be one of the most aggressive of the clownfishes. They will not get along well with any other clownfish in the same tank unless they are a mated pair. Even hobbyists keeping them in very large aquariums have reported aggression amongst the Maroon Clownfish and the other clowns in their tank. They do have the same characteristic
