🐠 Maroon Clownfish (Premnas biaculeatus)
A Deep Maroon-Red Body With Three Bold White Bars • The Largest Clownfish Species • A Bold, Captivating Showpiece
📋 The Maroon Clownfish displays the classic wild-type pattern: a deep maroon-red body marked with three bold white bars, one behind the eye, one at mid-body, and one at the base of the tail. It's the largest clownfish species, with females dwarfing males as they mature.
It comes from reefs across the Indo-Pacific, and wild Maroon Clownfish readily host in Bubble Tip Anemones, though a host isn't required in captivity. Every Maroon Clownfish we ship is feeding well, and we favour captive-bred stock, which is noticeably calmer and better adapted to aquarium life than wild-caught individuals.
It's the boldest, most confident clownfish species in the hobby, so keep it as the only clownfish in the tank, away from other species. It also carries a pair of sharp cheek spines beneath each eye, literally what "biaculeatus" means, so handle it with care, especially around hands and nets. It's fully reef safe. It reaches up to 15cm for females, with males roughly half that size, so plan on at least 115L, and larger is better given its adult size and temperament.
