Radiant wrasse
The radiant wrasse is a small marine fish of the family Labridae, native to reefs of the eastern Indian Ocean and western Pacific. It has a warm orange to reddish body with lighter markings, a dark spot on the head or nape, and blue and green highlights, showing brighter coloration in terminal-phase males. It is a peaceful, active wrasse that buries itself in the sand at night and when alarmed, and can be kept singly or in small groups. It requires a fine sand bed for burrowing, ample live rock, and a secure lid since wrasses are prone to jumping. It is a carnivore feeding on small invertebrates such as copepods, amphipods and small worms, and it helps control pest fauna; it should also be offered frozen and prepared meaty foods. Reef-safe and hardy once established, it is a good active swimmer for reef aquariums and mixes well with other peaceful fish.
