These are secretive gobies—sometimes stunningly attractive—that will spend most of their time hiding in reef crevices or under rocks or rubble. Some prefer a cave in which they will perch, upside down, on the ceiling.

Because of their cryptic behavior, they are not the best display animals. You may not see them for weeks or even months. Some individuals will pop out of hiding when food is added to the aquarium. Others will wait for the food to make its way into their hiding places before feeding. You are more likely to see them in a nano-reef aquarium with no intimidating tankmates.

One species, Priolepis nocturnus, will readily spawn in captivity. Eggs are deposited on the ceiling of a cave or overhang and are guarded by the male.
