Appearance
They usually have a bright yellow head, merging into a white body, gradually shading into a red-orange tail. Their dorsal fins are very long, and the fish flicks it back and forth. This is used as a signal to conspecifics. As a full grown adult, it reaches a maximum length of 9 centimeters. Adults occupy sandy burrows alone or in pairs, while the juveniles live in small groups. These fish are monogamous. They will retreat to burrows if threatened.
Habitat
It is usually found just above the bottom, facing into the current, where it awaits its prey of small invertebrates.References:
