The Red Sea Mimic Blenny, Ecsenius gravieri is a marine-reef species that belongs to the combtooth family (Blenniidae). They can grow up to 8 cm. These fish are yellow and green in coloration with a series of black markings that follow the lateral line of the fish. The Red Sea Mimic Blennies are herbivores and feed on algae and plants. In general, their food must be small enough to just swallow since they are unable to chew. Because this species is generally peaceful and enjoys beautiful color and shape, they are good candidates for aquarium’s trade.
Even though the Red Sea Mimic Blenny lacks the venomous bite against predators which is considered a self-defense mechanism of other blennies (e.g. black-lined blenny), the mimicking of the red Sea mimic blenny to the venomous species would help their survival, as predatory fish typically pass them by.
