A 10 gallon or larger aquarium with plenty of rock and hiding places is the optimal environment for a Mexican Barnacle Blenny. These fish are extremely energetic and entertaining, often dashing through the water column to grab food while avoiding other fish. They are also very alert and spend much of their time surveying their environment for potential meals. This species is known to take up residence in cracks and crevices, meaning they are rarely seen in the open. As a result, you can enjoy the antics of the Mexican Barnacle Blenny without being able to actually see them. Furthermore, they are hardy and undemanding, making them a great addition to any aquarium.

The Mexican Barnacle Blenny is an interesting and unique aquarium fish species that will add a splash of color to your home aquarium. It is a hardy and resilient fish that does best in well-established aquariums with a good amount of crevices in the rocks for it to hide and feel safe. A diet rich in meaty items such as finely chopped crustacean flesh, vitamin enriched frozen brine and mysis shrimp will ensure that your Mexican Barnacle Blenny is healthy and happy. To further ensure their wellbeing, the tank should have a high water quality and a stable, consistent temperature.
