Linear Blenny - Maldives

Ecsenius lineatusThe Linear Blenny is a small, striking reef fish that adds both color and activity to a marine aquarium. Adults feature a pale lower body with a tan to yellowish-green upper body, decorated with horizontal white to yellow lines and a series of black rectangular blotches along the sides, creating a distinctive linear pattern. Like other blennies, they lack a swim bladder and spend much of their time perched on rocks or darting between crevices, so an aquarium with plenty of rockwork, ledges, and hiding spots is essential. Linear Blennies typically grow to about 3.5 inches (9 cm) and are suitable for tanks of 30 gallons or larger. They are generally peaceful but may defend their perch from other blennies. A tight-fitting lid is recommended, as they are known to jump. In the wild, this species is found across shallow coral reefs and rocky areas of the Indo-West Pacific, including southern Oman, the Philippines, northern Australia, and southern Japan. Omnivorous by nature, Linear Blennies thrive on a varied diet of algae-based foods, spirulina pellets, and frozen items like mysis or brine shrimp. Feeding twice daily helps maintain their vibrant coloration and overall health. Considered reef-safe, they do not harm corals or invertebrates, and their natural grazing helps control algae growth, making them both a beautiful and functional addition to the aquarium.
