Flame Fairy Wrasse (Cirrhilabrus jordani)

A Hawaiian endemic, meaning this species doesn't naturally occur anywhere else on the planet, the Flame Fairy Wrasse carries a vivid red-orange coloring that gets more intense on males as they mature and compete for the attention of females. Fairy wrasses are active, constantly cruising swimmers that spend the whole day picking through rockwork for tiny invertebrates, and they're one of the better answers to a pest amphipod or bristleworm population running slightly out of control. They're also known jumpers, which is a polite way of saying they will find any gap in your lid and take it, so a tight-fitting cover isn't optional with this one.
