Common name: Cockscomb firefish

General information

The Red Sea Mimic Blenny, scientifically known as Ecsenius bleekeri, is a captivating species that adds both character and utility to a saltwater aquarium. This species is known for its remarkable ability to mimic the patterning and behavior of the venomous Meiacanthus blennies, a form of Batesian mimicry that deters potential predators. The Red Sea Mimic Blenny is a small, elongated fish with a maximum length of around 10 centimeters, displaying a range of colors from yellow to brown with dark longitudinal stripes.

Care

Red Sea Mimic Blennies are hardy and adaptable, making them suitable for both beginner and advanced aquarists. They thrive in well-established aquariums with plenty of live rock for grazing on microalgae and hiding. These blennies are generally peaceful but can exhibit territorial behavior towards other blennies or similarly shaped fish. A varied diet of algae-based foods and meaty items like mysis shrimp will keep them healthy and vibrant.

Reproduction

In the wild, Ecsenius bleekeri are oviparous, with males often guarding and caring for 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

Native to the Red Sea, the Red Sea Mimic Blenny is typically found in shallow, coral-rich environments and reef slopes. They are adept at navigating the complex structures of the reef, which provides them with food, shelter, and protection from predators.
