The Bluespotted Watchman Goby, commonly referred to as the Blackfinned Shrimp Goby, was first discovered by Bleeker in 1849. There are 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.
It should be housed in a 30 gallon or larger aquarium with plenty of loose coral rubble. It requires ample swimming room and a sand bottom for burrowing. Rarely will it become aggressive towards other fish, but it is territorial, and will fight with its own kind unless they are a mated pair. The aquarium requires a tight-fitting cover to prevent it from jumping out.
The Bluespotted Watchman Goby feeds mostly on prey suspended in the water column but will pick food off the substrate. The diet should include mysid shrimp, brine shrimp, and table shrimp. It should be fed at least three times per day.

Minimum Tank Size: 30 gallons

Tank Conditions: 72-78°F; sg 1.020-1.025; pH 8.1-8.4; dKH 8-12
Max. Size In Aquarium: Up to 5"

Origin: Caribbean, Eastern Pacific
Family: Blenniidae
The Horseface Blenny, also known as the Panamic Fanged Blenny, originates in the Caribbean Ocean. Its body is a blended black and red with yellow markings camouflaging the body and fins. The head of this fish carries 4 small branching horns, and the nose is very blunt, which gives this species a unique horse-like appearance.
A well-established 30-gallon or larger aquarium with multiple swimming levels and plenty of rock is a suitable environment. It is not usually aggressive unless the tank mates appear to have a similar shape as it does. It is best to house singly unless kept in a larger tank and the two are a mated pair. It tends to perch and hop from rock to rock looking for microalgae to graze on. It is known to nip at small-polyped stony coral and clam mantles.
The Horseface Blenny does best in well-established aquariums with large amounts of natural algae to feed on. The diet can be supplemented with vegetable matter, Spirulina, and herbivore preparations.
