The Jeweled Blenny is also referred to as Jewelled Rockskipper or the Lawnmower, Sailfin/Algae, or Rock Blenny. Its body is a mottled tan with blue dots.

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 Jeweled 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.
