General information

The Molly Miller Blenny, Scartella cristata, is a distinctive and beneficial species for marine aquariums. Known for its unique appearance with a mottled pattern of brown and white, and a characteristic 'sailfin' on its head, this blenny is a small, hardy fish that can adapt to various environments.

One of the most notable behaviors of the Molly Miller Blenny is its propensity for algae grazing, making it a valuable addition to control unwanted algae growth in the aquarium. It is also known for its curious and personable nature, often becoming a favorite among aquarists for its interactive behavior.

Care

Molly Miller Blennies are relatively easy to care for, requiring a tank with plenty of live rock for grazing and hiding. They are not picky eaters and will accept a variety of foods, including algae, frozen and dried foods. However, ensuring a diet that includes algae or vegetable matter will help maintain their health and vibrant colors.

Reproduction

In the wild, Molly Miller Blennies are protogynous hermaphrodites, meaning they start life as females and can change to males if needed. In the aquarium, breeding is less common, but with a well-established environment and a pair, it is possible to observe their fascinating breeding behaviors.

Habitat

Native to the Atlantic Ocean, the Molly Miller Blenny can be found in a range of habitats from shallow reefs to seagrass beds. They are adept at finding crevices and small caves in the rockwork to call home, and in the aquarium, they appreciate similar conditions that provide security and foraging opportunities.
