Red Sea Mimic Blenny

Red Sea Mimic Blenny

Ecsenius gravieri

A Batesian mimic that copies the venomous sabretooth blenny (Meiacanthus nigrolineatus) in both color and its off-the-bottom gliding swim, so predators leave it alone even though it is itself completely harmless. A jewel of a nano fish: a sky-blue body, sunrise-yellow face, and a bold black eye-stripe. It grazes algae and picks at the rock, but keep only one per tank and watch clams and stony corals, as it can nip mantles and polyps. A Red Sea endemic that is almost always wild-collected.
