The Cirrhilabrus Rubromarginalis or Red Margin Fairy is a beautiful wrasse that is endemic to the waters of southern Japan and Indonesia. Usually seen in pairs, it is known to exhibit a very eye-catching coloration with red margins on both its tail and dorsal fin. A male Red Margin Fairy is known to exhibit better color intensity as compared to a female or juvenile. However, the male wrasses tend to look duller as compared to their female counterparts during courtship. The Pink Margin Fairy Wrasse requires a tank with a tight lid to prevent escapes.
