The Citron Clown Goby, Gobiodon citrinus, also known as the Citron Goby, Poison Goby, and Rusty Goby, is a small, peaceful fish that is easy to care for. It features a yellow/orange body with unique markings across its face. They can be kept singly or in pairs. Like other Goby species, the Citron Clown Goby will often create its own burrow in the sand – sometimes these burrows are shared in a symbiotic relationship with the Pistol Shrimp. Therefore, a tank with plenty live rock, a sandy substrate, and a tightly sealed lid to prevent escapes is recommended. The Citron Clown Goby should not be housed with larger predatory fish for its small size could easily make it prey. They will take a carnivorous diet of small frozen foods. Overall, a great easy to care for reef safe fish.
