The Koi Fairy Wrasse, Cirrhilabrus sp., is a vibrantly colored fairy wrasse native to the Indian Ocean. Males and females exhibit highly differentiated body types. Females are generally larger, have more subdued colors on pinks and oranges, while males are far more gaudy in their appearance having bright and variable colors of reds, blues, oranges, and pinks. The Koi Fairy Wrasse should be kept in a tankwith plenty of rock structures for it to explore and hide in. A tight lid should be kept on your tank to prevent it from escaping.
