Care

Zebra 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 and hiding. These fish are herbivores, primarily feeding on algae, so it's important to ensure a steady supply of macroalgae or prepared algae-based foods.

Reproduction

In the wild, Zebra Blennies are known to lay eggs in crevices or under ledges. In captivity, breeding can occur if a pair is well-established and the environment is stable. The male typically guards the nest site and aerates the eggs until they hatch.

Habitat

Native to the Indo-Pacific region, Zebra Blennies are commonly found in shallow, rocky coastal areas and tide pools. They are adept at maneuvering through crevices and are often observed hopping from rock to rock, hence the name 'Rockskipper'.
