A well-established 30-gallon or larger aquarium with multiple swimming levels and plenty of rock is a suitable environment for this species. It is hardy and relatively peaceful, but may become aggressive if other tank mates appear to be similar in shape. To avoid any territorial disputes, it is best to house this species singly unless kept in a larger tank with a mated pair. This species is known to perch and hop from rock to rock looking for microalgae to graze on, as well as nipping at small-polyped stony coral and clam mantles. To ensure the wellbeing of your aquarium and its inhabitants, it is important to monitor this species behavior and to provide plenty of hiding places. Furthermore, it is best to avoid housing this species with more aggressive tank mates.

The Horseface Blenny is a hardy addition to aquariums, and can thrive in well-maintained environments with ample amounts of natural algae. A balanced diet should also be provided which can include vegetable matter, Spirulina, and herbivore preparations. This fish is an excellent choice for those looking for an easy-care, algae-eating fish. Proper care should be taken to ensure that the aquarium is kept clean and the tank is well-filtered. Additionally, the water parameters should be monitored regularly to keep the environment stable and healthy for the blenny.

One-and-a-half to three inches is about the approximate purchase size for these earrings.
