Care

Lined Blennies are hardy and adaptable, making them suitable for both beginner and experienced hobbyists. They thrive in well-established aquariums with plenty of live rock for perching and hiding. These omnivores will accept a variety of foods, including algae, frozen and dried preparations, and meaty foods.

Reproduction

In the wild, Lined Blennies are known to lay eggs in crevices or under ledges. In the aquarium, breeding is less common, but with a well-maintained environment and a compatible pair, it is possible to observe their fascinating mating rituals and care for their young.

Habitat

Istiblennius lineatus is found in shallow, coastal waters, often in tide pools and rocky crevices. They are widespread in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific Ocean.
