Common name: striped blenny

General information

The Lined Blenny, scientifically known as Ecsenius lineatus, is a small, colorful fish that is a favorite among marine aquarists. This species is known for its distinctive horizontal stripes that run the length of its body, which can range in color from bright blue to deep purple, depending on the individual and the lighting conditions. The Lined Blenny is a member of the Blenniidae family, which is characterized by their comb-like teeth and a continuous dorsal fin.

These blennies are not only admired for their striking appearance but also for their interesting behavior. They are often seen perching on live rock or coral, darting in and out of crevices, and displaying a curious and watchful demeanor.

Care

Lined Blennies are relatively easy to care for, making them suitable for both novice and experienced aquarists. They thrive in well-established aquariums with plenty of live rock for hiding and grazing. It's important to provide a varied diet that includes algae and meaty foods to maintain their health and coloration.

Reproduction

In the wild, Lined Blennies are oviparous, with males often guarding and aerating the eggs until they hatch. While breeding in captivity is less common, providing a stress-free environment with plenty of hiding spaces can encourage reproductive behavior.

Habitat

Lined Blennies are found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They prefer shallow, coral-rich environments and are often found at depths ranging from just below the surface to about 30 meters. Their natural habitat includes reef flats, lagoon pinnacles, and seaward reefs, where they utilize the complex structures for shelter and foraging.
