Tailspot Blenny Fish

The Tailspot Blenny, *Ecsenius stigmatura*, is a charming and active addition to the home aquarium. This small blenny is easily recognized by the prominent black spot at the base of its tail, contrasting with its generally tan to light brown body and often speckled or mottled pattern. They have a distinctive elongated body shape and spend much of their time perched on rocks or other surfaces, observing their surroundings.

A minimum aquarium size of 10 gallons is recommended for a single Tailspot Blenny. They appreciate a well-established tank with plenty of live rock offering numerous crevices and hiding places. While generally peaceful, they can be territorial towards other blennies or fish with similar body shapes. They are considered reef safe and will not typically bother corals or invertebrates.

Tailspot 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 enriched brine shrimp. Providing a varied diet is essential for their long-term health. In the aquarium, they typically reach a size of about 2.5 inches. There are no readily apparent visual differences between males and females.
