Acanthemblemaria stephensiis commonly referred to as Malpelo barnacle blenny. Difficulty in the aquarium: There are no reports available yet that this animal has already been kept in captivity successfully. Toxicity: Toxic hazard unknown.
Very special thanks for the first two photos of Acanthemblemaria stephensi to Dr. Ross Robertson, Australia.
He has taken the photos at Malpelo Island, Colombia in the Eastern Pacific where the barnacle blenny lives reef-associated in empty barnacles and worm or mollusk tubes on rocky reefs in crevices and deep recesses in the rocks.
The blenny is considered to be locally common at Malpelo Island, the fish lives endemic here.
