Jewelled Rockskipper (Sailfin / Lawnmower Blenny)
One of the most underrated reef fish out there—the Jewelled Rockskipper is packed with personality and purpose. Also known as the Lawnmower Blenny, this quirky little character is constantly on the move, perching, hopping, and grazing across your rockwork.
With its mottled pattern, oversized eyes, and classic blenny attitude, it brings both visual interest and real utility to your tank. These guys are natural algae grazers, helping keep nuisance algae under control while staying peaceful with most other fish.
They thrive in established reef tanks with plenty of live rock, where they can graze naturally and explore. Watching them hop from rock to rock and claim little perches around the tank is half the fun.
