Common name: Mimic Blenny

General information

The Mimic Blenny, scientifically known as Ecsenius pulcher, is a captivating and colorful addition to any marine aquarium. This species is renowned for its remarkable ability to mimic other fish, particularly the Meiacanthus genus, which includes the venomous fang blennies. This mimicry serves as a defense mechanism, deterring potential predators by imitating the appearance and behavior of the less palatable fang blennies.

Care

Mimic Blennies are relatively hardy and can adapt to life in captivity. They thrive in well-established aquariums with plenty of live rock for grazing and hiding. These fish are herbivores, primarily feeding on algae, so it's important to provide them with a diet that includes high-quality marine algae and prepared foods that contain spirulina or other plant-based nutrients.

Reproduction

In the wild, Mimic Blennies are oviparous, with males often establishing territories and courting females by performing elaborate displays. After spawning, the female lays adhesive eggs in a secure location, which the male then guards and aerates until they hatch.

Habitat

Ecsenius pulcher is found in the Indo-Pacific region, from the Maldives to the Philippines, and as far south as Indonesia. They are commonly associated with coral reef environments, where they can be seen darting in and out of crevices in search of food or shelter.
