Priolepis cincta

The Girdled Reefgoby, Priolepis cincta, is a small goby fish reaching a maximum length of 7 cm. It is easily recognized by its distinctive pattern of alternating dark-edged brown and narrower white bars on its head and body. The dorsal and caudal fins are adorned with brown spotting, and the basal part of the dorsal fins features dark spots or bands. This species has a fusiform body shape with a compressed cross-section, and it lacks scales on its cheeks. This goby is found in the Indo-West Pacific region, ranging from the Red Sea and the Persian Gulf to the islands of Micronesia, Fiji, and Tonga, and from Japan to the Coral Sea. It inhabits both brackish and marine environments, typically at depths of 1 to 30 meters, although it can be found as deep as 70 meters. The Girdled Reefgoby is a reef-associated fish, often seen hiding in caves, crevices, and among corals or rocks. The species exhibits monogamous behavior and is known to be a benthic spawner. It is also capable of bi-directional sex change, which is an aspect of its reproductive strategy. The Girdled Reefgoby is harmless to humans and is of commercial interest for aquariums. According to the IUCN Red List, it is categorized as Least Concern.
