Exalias Brevis

Leopard Blenny

The Leopard Blenny (Exallias brevis) is a beautiful and unique marine fish known for its striking, leopard-like spotted pattern. Its body, which can range in color from cream-white to pink, is adorned with clustered spots that vary from brownish to orange, red, and even purplish. This intricate pattern serves as excellent camouflage on the corals they inhabit in their natural environment.

Important Note for Aquarists: The Leopard Blenny is an obligate corallivore, meaning its primary diet in the wild consists exclusively of coral polyps. This species is not recommended for a typical reef aquarium as it will actively feed on and damage your stony corals (SPS), such as Acropora and Porites. They can only be kept successfully in a large, dedicated system with an abundant supply of fast-growing corals.
