Care
Rockskipper Blennies are hardy and adaptable, making them suitable for both novice and experienced aquarists. They thrive in tanks with plenty of live rock and crevices for hiding and grazing on algae. These blennies are herbivores and require a diet rich in marine algae and vegetable matter to maintain their health and coloration.
Reproduction
In the wild, Rockskipper Blennies are known to lay eggs in crevices or under rocks. In the aquarium, breeding is less common, but with a well-established environment and a pair, hobbyists may observe spawning behavior. The male typically guards the nest until the eggs hatch.
Habitat
Istiblennius edentulus is found in shallow, coastal waters and tide pools, often in areas with strong surge and wave action. They are adept at clinging to rocks and can often be seen out of the water during low tide. Their natural range extends across the Indo-Pacific region, from the eastern coast of Africa to the islands of the central Pacific.
