Molly Miller Blenny Fish

The Molly Miller Blenny, *Scartella cristata*, is a charming and active addition to the home aquarium. This small blenny is typically mottled brown and tan, providing excellent camouflage among rockwork. They possess distinctive cirri (small fleshy filaments) above their eyes, giving them an inquisitive appearance.

A minimum tank size of 10 gallons is recommended for a single Molly Miller Blenny. Provide plenty of live rock with crevices and hiding places, as they are benthic (bottom-dwelling) and enjoy perching and exploring their surroundings. They are generally peaceful and can be kept with other non-aggressive fish.

Molly Miller Blennies are primarily herbivores and omnivores. Their diet should consist of a variety of marine algae, spirulina, and high-quality flake or pellet foods designed for herbivores. They will also readily accept small meaty foods such as mysis shrimp or brine shrimp. In a well-established tank with live rock, they will also graze on naturally occurring algae.

In the home aquarium, Molly Miller Blennies typically reach a size of around 3-4 inches. They are known for their personality and entertaining behavior, often “hopping” or “walking” across the substrate and rockwork. They are relatively hardy and a good choice for beginner to intermediate aquarists. Sexing is difficult, and breeding in captivity is not commonly reported.
