The Green Clown Goby is a small species known from lagoons and reef crests to depths of around 15m.
.The Green Clown Goby are perfect fish for any sized reef especially nanos because they stay nice and small. They do not swim much around the tank but instead look for a spot to perch and watch what's going on. The Green Clown Goby will often perch among the branches of SPS corals but can decide to rest on other types as well. They rarely do any real harm to the corals. They can be tough to feed but only because of the size of their mouths. The Green Clown Goby will readily accept any type of marine foods you offer as long as they are small enough to get down. In very small tanks they can possibly be aggressive towards other clown gobies, but some will pair up.
