Description
The Horned Rockskipper is a fascinating marine blenny characterized by the prominent cirri above its eyes, giving it a 'horned' appearance. This bottom-dwelling fish primarily grazes on algae but will also consume small invertebrates. They are territorial and require plenty of rockwork and hiding spots in an aquarium.
