The Bluespotted Watchman Goby has two color phases. The first has an orange head with blue spots, the body is orange with red bands, and the dorsal fin has black spots. The second phase is olive drab with blue spots. The aquarium should copnsist of plenty of loose coral rubble with ample swimming room and a sand bottom for burrowing. It will not become aggressive towards other fish, but it is territorial, and will fight with its own kind unless they are a mated pair. The Bluespotted Watchman Goby's diet should consist of meaty preparations either fresh or frozen.
