Blenny Care Guide

Blennies are small, bottom-dwelling reef fish known for their expressive faces, quirky perching behavior, and usefulness in controlling nuisance algae.

Algae Control

Species like the lawnmower blenny are prized for actively grazing on algae growing on rock and glass, making them a functional as well as decorative addition to a reef tank.

Tank Requirements

Blennies appreciate plenty of rockwork with small caves to retreat into and perch on throughout the day.

Temperament

Most blennies are peaceful, though some can be territorial toward other bottom-dwelling fish of similar shape.

Reef Compatibility

Blennies are generally considered reef-safe and make a great addition to the clean-up crew alongside snails and hermit crabs.
