Common name: Comical blenny

General information

The Frontier Blenny, scientifically known as Ecsenius opsifrontalis, is a small and colorful marine fish that is a member of the combtooth blennies family Blenniidae. This species is known for its distinctive coloration and behavior, making it a charming addition to any reef aquarium. The Frontier Blenny has a unique color pattern with a combination of blue, yellow, and white hues that can vary depending on the individual and its environment.

Care

Frontier Blennies are hardy and adaptable, making them suitable for both beginner and experienced aquarists. They thrive in well-established aquariums with plenty of live rock for grazing on microalgae and hiding. These fish are generally peaceful but can be territorial towards other blennies. A varied diet of marine algae, vegetable matter, and meaty foods will help maintain their health and coloration.

Reproduction

In the wild, Frontier Blennies are oviparous, with males often guarding and aerating the eggs until they hatch. In the aquarium, breeding can occur if a compatible pair is established, and the environment is stable and well-maintained.

Habitat

Ecsenius opsifrontalis is found in the Western Pacific, particularly around Indonesia and the Philippines. They inhabit shallow reef flats and lagoons, often seen perching on coral heads or rock outcroppings. They prefer areas with moderate to strong water movement and access to plenty of microalgae growth.
