General information

The Tailspot Blenny, scientifically known as Ecsenius stigmatura, is a charming and popular fish among reef aquarium enthusiasts. This small, colorful blenny is known for its distinctive dark spot at the base of its tail, which gives it its common name. It has a comical and endearing personality, often seen perching on coral or rockwork, observing its surroundings with keen interest.

Tailspot Blennies are herbivores, primarily feeding on algae in their natural habitat. They are a peaceful species and can be a great addition to a community tank, provided they are housed with non-aggressive tank mates.

Care

Tailspot Blennies are relatively easy to care for, making them suitable for both beginner and advanced aquarists. They require an established tank with plenty of live rock for grazing on microalgae and for hiding. These blennies are known to jump, so a tank with a secure lid is recommended to prevent escape.

A varied diet that includes marine algae, vegetable matter, and high-quality prepared foods will help maintain their health and vibrant colors. It's important to ensure that they have a constant supply of natural or supplemented algae to graze on.

Reproduction

In the home aquarium, breeding Tailspot Blennies can be a challenge. They are not commonly bred in captivity, and little is known about their breeding behaviors in the wild. However, like many blennies, they are likely to be oviparous, with the male guarding and caring for the eggs until they hatch.

Habitat

Ecsenius stigmatura is found in the Indo-Pacific region, from the Maldives to the Philippines, and as far south as Indonesia. They inhabit shallow coral reefs and lagoons, often found in crevices or among the branches of stony corals. They are typically seen at depths ranging from just below the surface to about 25 meters.
