Care

Nocturnal Gobies are relatively easy to care for but do require a well-established aquarium with plenty of live rock and hiding places. They are shy and peaceful, making them suitable tank mates for other non-aggressive fish. A sand substrate is also beneficial as they enjoy burrowing. They feed on a variety of foods including small crustaceans and should be offered a diet that includes frozen and live foods to ensure proper nutrition.

Reproduction

In the aquarium, Priolepis nocturna can spawn if provided with the right conditions. A bonded pair will lay eggs in a secure cave or crevice, and the male will guard the eggs until they hatch. Breeding these gobies in captivity can be challenging but rewarding for experienced aquarists.

Habitat

The Nocturnal Goby is found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They typically inhabit coral reefs and lagoons, often taking refuge in rubble or among the branches of corals. They are adept at navigating the complex structures of the reef, which provides them with protection from predators and access to food sources.
