General information

The Rock Blenny, Labrisomus philippii, is a small, charismatic fish known for its distinctive appearance and behavior. It is a member of the family Labrisomidae, which includes various species of blennies that are popular in the marine aquarium hobby. Rock Blennies have a mottled brown and tan coloration that helps them blend into their rocky surroundings, and they are recognized by their elongated bodies and the presence of small cirri (whisker-like appendages) above their eyes.

Care

Rock Blennies are hardy and adaptable, making them suitable for both beginner and advanced aquarists. They thrive in aquariums with plenty of live rock for hiding and grazing on microalgae. These fish are known for their voracious appetite for algae, which makes them beneficial for controlling algae growth in the tank. They are generally peaceful but can be territorial towards other blennies or similarly shaped fish.

Reproduction

In the wild, Rock Blennies are oviparous, with males often guarding and aerating the eggs until they hatch. Breeding them in captivity can be challenging, and hobbyists interested in breeding should provide a separate breeding tank with optimal conditions for egg laying and development.

Habitat

Labrisomus philippii is found in the Eastern Pacific, from the Gulf of California to Peru, including the Galapagos Islands. They inhabit shallow, rocky reefs and are often seen perching on rocks or coral heads, surveying their territory. In the aquarium, they require a setup that mimics their natural habitat with ample rockwork and a moderate to strong water flow.
