Care

Half-barred Gobies are relatively easy to care for, provided their basic needs are met. They thrive in well-established aquariums with plenty of live rock for hiding and foraging. A sandy substrate is also beneficial as they occasionally burrow. These gobies are carnivorous, feeding on small invertebrates and zooplankton in the wild, so a varied diet of meaty foods such as brine shrimp, mysis shrimp, and finely chopped seafood is recommended.

Reproduction

In the aquarium, Priolepis semidoliata may breed if kept in a pair or small group, provided they have a stress-free environment. They lay eggs in a secure cave or crevice, and the male typically guards the eggs until they hatch. Breeding these gobies can be a rewarding experience for the dedicated hobbyist.

Habitat

Half-barred Gobies are found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They inhabit coral reefs and lagoons, often seen in shallow waters hiding among corals and rubble. Their natural habitat includes areas with moderate to strong water movement.
