Description

A tiny, stocky coral-dwelling goby with a large head, yellow-green to olive body and orange-red bars radiating across the face and gill cover. Peaceful and largely sedentary, it perches inside branching SPS colonies (Acropora, Seriatopora) and rarely leaves its host, so it thrives in small mature reef tanks with plenty of branch structure and few boisterous tankmates. It is generally reef safe, though pairs may nip or clear polyps on the coral they claim as a nest site, and its skin secretes a bitter toxic mucus that deters predators.

Reef Safe

With caution

Environment

The Green Clown Goby thrives in a well-maintained reef aquarium with plenty of live rock and coral for hiding and perching. It prefers a stable environment with a temperature range of 72-78°F, a pH of 8.1-8.4, and a specific gravity of 1.020-1.025.

Behavior

This species is generally peaceful and can often be found perching on coral branches. It is known to form symbiotic relationships with certain coral species, where it finds shelter and protection.
