Care

Tank and decor: live rock with holes to perch in. The tank size given is an estimate. Little is given in our sources beyond the aquarium list; the notes below are general guidance for this kind of fish. Water: the sources give no species-specific figures, so the values here are general marine aquarium guidance: 24–27 °C, pH 8.1–8.4 and specific gravity 1.023–1.026. Keep nitrate low and the water well oxygenated. Identification: a blenny of up to about 9 cm. Sources: Wikipedia, List of marine aquarium fish species (en.wikipedia.org/wiki/Listofmarineaquariumfishspecies). Checked October 2026.

Diet

Our sources give no diet. Provide algae growth to graze plus small frozen foods.

Breeding

Not described in our sources.

Compatibility and tank mates

Reef safe according to the list. May squabble with other blennies.
