Difficulty

Easy

Temperament

Semi-Aggressive

Description

A stout, mottled tan-to-olive combtooth blenny marked with dark bars and a crest of hair-like cirri across the head, with large expressive eyes and a habit of perching and hopping across rockwork. It is one of the most useful clean-up fish in the hobby, grazing film algae, microalgae, detritus and often picking off Aiptasia anemones, and it is hardy, boldly personable and readily aquacultured. Give it a mature 30-gallon or larger tank with abundant live rock and crevices; it is generally peaceful but will squabble with similarly shaped bottom-dwelling blennies and gobies, so keep one per tank unless the system is large.

Reef Safe

Yes

Environment

The Molly Miller Blenny thrives in a well-established marine aquarium with plenty of live rock for grazing and hiding. It prefers water temperatures between 72-78°F, a pH of 8.1-8.4, and a specific gravity of 1.020-1.025.

Behavior

This fish is known for its active and curious nature, often seen darting around rocks and crevices in search of food. It is an excellent algae eater and can help keep the tank clean.
