Known for their stunning sexual dimorphism (difference between males and females), these fish are a captivating addition to a mature marine aquarium.\u003c\/p\u003e\n\u003ch4\u003eAppearance:\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMale:\u003c\/strong\u003e Males are predominantly pink to reddish-pink with a lavender or purplish belly. Their most distinguishing feature is a bold, squarish or rectangular patch of purple or magenta on their flanks, located just behind the pectoral fin, which gives the fish its common name. The dorsal fin is often elongated.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFemale:\u003c\/strong\u003e Females have a vibrant yellow to yellow-orange body with a lavender wash on the belly. They generally lack the prominent square patch and instead may feature a thin blue line extending from the snout to the pectoral fin.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGeneral:\u003c\/strong\u003e Like all anthias, they are active, mid-water swimmers that bring a beautiful flash of color to the water column, particularly when kept in a group.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eUnique Characteristics:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAll Anthias species are hermaphroditic. They live in a harem structure, typically consisting of one dominant male and several females. If the male is removed or perishes, the largest female in the group will often undergo a sex change to become the new dominant male.\u003c\/p\u003e\n\u003ch3\u003eCare Information\u003c\/h3\u003e\n\u003ch4\u003eAquarium Requirements\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTank Size \u0026amp; Setup:\u003c\/strong\u003e A minimum of 100 gallons is needed for a single Squareback Anthias, while a group requires a larger aquarium of 180 gallons or more to provide sufficient swimming space and territory. They thrive in established tanks with mature filtration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSocial Structure:\u003c\/strong\u003e This species does best when kept in a social group, ideally a harem consisting of one male and several females. If multiple males are introduced without adequate space and a large number of females, aggression will be high. Always introduce females before introducing a male.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAquascaping:\u003c\/strong\u003e Provide ample live rock with numerous caves, overhangs, and crevices.
