Males are especially striking, developing elongated finnage and intensified colours during courtship, while females remain more subdued. In the wild, this species lives along outer reef slopes over rubble, algae and coral, where it is found in small mixed-sex groups. In aquaria it is a lively but generally peaceful fish that does best in a mature marine system with swimming room, rockwork and a secure lid.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCommon Name:\u003c\/strong\u003e\u003cbr\u003eMcCosker’s Flasher Wrasse.
