Longfin Fairy Wrasse (Cirrhilabrus rubriventralis)

Most Cirrhilabrus wrasses put their energy into color; this one puts some of it into fin length instead, trailing elongated fins that flutter behind it as it swims through open water. Otherwise it's a standard fairy wrasse story: a harem structure, a female-to-male sex change in the dominant fish, and constant, restless motion through the tank.
