Two-Spot Goby

The Two-Spot Goby is one of the most fascinating and behaviorally unique gobies available to marine aquarists. Its most distinctive feature is the pair of large, dark eyespots (ocelli) prominently displayed on each dorsal fin, which the goby raises and flares when threatened. This remarkable threat display is thought to mimic the appearance of a much larger predator's eyes, startling potential attackers and buying the goby precious seconds to retreat to safety. The behavior is mesmerizing to watch and sets this species apart from all other aquarium gobies.

The body of the Two-Spot Goby is white to pale gray with brown to reddish-brown bars and markings. Adults reach about 3 inches in length. In the wild, this species inhabits sandy patches near reef rubble, where it sifts through the substrate for small invertebrates and organic matter. It is typically found in pairs that maintain a shared territory and burrow. The combination of its unique dorsal fin display, pair bonding, and sand-sifting behavior makes it one of the most behaviorally interesting gobies for the home aquarium.

Despite its appeal, the Two-Spot Goby can be moderately challenging to maintain long-term. It requires a mature sand bed with abundant microfauna to supplement its diet and can be difficult to wean onto frozen foods initially. Patience during acclimation and a well-established tank are key to success with this species.
