Common name: White-lined coralblenny

General information

The Lined Combtooth Blenny, scientifically known as Ecsenius taeniatus, is a small, colorful fish that is a popular choice among reef aquarium enthusiasts. This species is part of the Blenniidae family and is known for its distinctive horizontal stripes that run the length of its body, which can range in color from blue to purple, with a pale underside.

These blennies are known for their curious and bold behavior, often seen perching on rocks or coral outcroppings, observing their surroundings. They have a comical appearance with large eyes and a blunt head, which adds to their appeal in a home aquarium.

Care

Lined Combtooth Blennies are relatively easy to care for, but they do require a stable and mature aquarium with plenty of live rock for grazing and hiding. They are herbivores, primarily feeding on algae, so it's important to ensure that there is a sufficient growth of natural algae in the tank or to supplement their diet with algae-based foods.

These blennies are generally peaceful but can be territorial towards other blennies or similarly shaped fish. They are best kept in a tank with plenty of space to establish their own territory.

Reproduction

In the wild, Lined Combtooth Blennies are oviparous, with males often guarding and aerating the eggs until they hatch. Breeding them in captivity can be challenging, and there is limited information available on successful captive breeding practices for this species.

Habitat

Ecsenius taeniatus is native to the Indo-Pacific region, commonly found in shallow, coral-rich areas and lagoons. They prefer to stay close to the reef structure, where they can quickly dart into crevices to avoid predators or to rest.
