The Bullseye Jawfish, Opistognathus scops, features a circular spot on its dorsal fin with a brown/black splotched body. This fish is beautiful, comical, peaceful, and entertaining to watch making it a great addition to any tank. Like other Goby species, the Bullseye Jawfish will often create its own burrow in the sand - sometimes these burrows are shared in a symbiotic relationship with the Pistol Shrimp. They will instinctively spit gravel at any fish that comes close to its burrow. They are best kept in tanks with plenty of live rock, a sandy substrate, and a tightly sealed lid to prevent escapes.
