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.
