Common name: Leopard blenny

Scientific name: Exallias brevis (Kner, 1868)

General information

The Leopard Blenny, also known as the Eyelash Blenny, is a distinctive and charismatic species known for its unique appearance and behavior. Exallias brevis is a member of the Blenniidae family and is often recognized by its leopard-like spots and protruding eyes that give it an 'eyelashed' look. Unlike many other blennies, the Leopard Blenny is not a herbivore but feeds primarily on live coral polyps, which can make it a challenging addition to a reef aquarium.

Care

Leopard Blennies require a well-established aquarium with plenty of live rock for hiding and grazing. They are best suited for fish-only or predator tanks due to their coral-eating habits. It's important to provide a varied diet that includes meaty foods, and they may accept high-quality frozen or prepared foods over time. Care should be taken to monitor their feeding to ensure they do not deplete coral populations in the tank.

Reproduction

In the wild, Leopard Blennies are oviparous, with males often guarding and aerating the eggs until they hatch. Breeding in captivity is rare, and little is known about their reproductive habits in home aquariums.

Habitat

Exallias brevis is found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They typically inhabit coral-rich areas of lagoons and seaward reefs, often seen perching on coral heads or hiding in crevices.
