Bay Blenny

(Hypsoblennius gentiles)

Hypsoblennius Blennies should be added to well established aquariums. Provide plenty of rockwork with caves and crevices to perch, hide or rest when needed. Hypsoblennius Blennies live in empty barnacles and can be territorial and aggressive of their home. Hypsoblennius Blennies may disturb small benthic invertebrates. Provide a diet rich in meaty and algae based foods several times daily. Males and females may have slightly differences. Most Blennies lack or have very small swim bladders. Be sure to provide an aquarium with a tight fitting lid as Blennies may jump.
