Care notes
Tank of at least 75 L with moderate lighting and plenty of live rock for grazing. Temperature 24-28°C, pH 8.1-8.4, salinity 1.020-1.025. It feeds mainly on algae but accepts spirulina-based foods and blanched vegetables. Avoid keeping with other herbivorous blennies as it may become aggressive. It can jump, so a lid is recommended.
