This reef-associated species is commonly found in seagrass beds, tidepools and coral reefs high-energy reef crests. A nocturnal species, it remains hidden in cracks and crevices during the day, before emerging to feed on plankton during the night. This species may reside in the rubble mounds made by the sand tilefish Malacanthus plumieri. Predated on by Lionfish. From depths of 1m to more than 100 m (3 to 300+ ft).
Males are mouth brooders and do not feed until the eggs hatch. The eggs in the oral cavity also impede respiration, hence such males are rather secretive and quiescent. They form distinct pairs during courtship and breed throughout the year.
