Circus Goby

Priolepis nocturna

Identification Small goby with alternating reddish-brown and white banding around the body, giving a ringed appearance. Bold pattern makes it stand out despite its small size.
Maximum Length Up to 2 inches (5 cm)
Origin Indo-Pacific
Minimum Tank Size 10 gallons
Reef Compatible Yes — excellent for nano and pico reef tanks

Behavior

A cryptic, cave-dwelling goby that hides among rockwork, rubble, and crevices. Peaceful and mostly nocturnal. Well suited to nano reef tanks where its small size and bold pattern can be appreciated up close.

Diet & Feeding

Carnivore. Feeds on small crustaceans and zooplankton. Offer frozen copepods, baby brine shrimp, and fine-grade reef foods. Ensure food reaches the bottom or rock areas where this goby hides.

Cautions

Very small — avoid housing with large or aggressive tank mates. May be out-competed for food.
