General information

The Smallspotted Combtooth Blenny, scientifically known as Parablennius pilicornis, is a charming and distinctive species popular among marine aquarium enthusiasts. This species is easily recognized by its mottled brown and white coloration, and the characteristic 'eyebrows'—fringed cirri above the eyes—that give it the nickname 'Eyebrow Barnacle Blenny'. They are small, reaching only about 11 centimeters in length, making them suitable for smaller marine aquariums.

Care

Smallspotted Combtooth Blennies are hardy and adaptable, making them a good choice for both beginner and advanced hobbyists. They thrive in aquariums with plenty of live rock for grazing on microalgae and hiding. These blennies are known for their curious and watchful behavior, often perching on high vantage points. They are generally peaceful but can be territorial towards other blennies. A varied diet of algae-based foods and meaty items like mysis shrimp will keep them healthy.

Reproduction

In the wild, Parablennius pilicornis are oviparous, with males guarding and aerating the eggs until they hatch. Breeding them in captivity can be challenging, but with a well-structured environment and careful attention to water quality, it is possible to encourage spawning.

Habitat

The Smallspotted Combtooth Blenny is native to the Eastern Atlantic, from the British Isles to Senegal, including the Mediterranean and Black Sea. They are typically found in shallow, rocky coastal waters where they can blend into their surroundings to avoid predators.
