Black Sailfin Blenny
Prized for its voracious appetite for nuisance microalgae, the Black Sailfin Blenny is most recognizable for its stark black coloration on both body and fins. Since the Black Sailfin Blenny eagerly perches upon live rock to feed, Atrosalarias fuscus truly creates an eye-catching addition to any saltwater reef system.
Black Sailfin Blenny is also known as the Dusky Blenny, Brown Coral Blenny, Black Blenny, Highfin Blenny, or Brown Combtooth Blenny. Males are generally larger than females and experience a succession of color changes when breeding.
These fish have a tendency to nip at clam mantles and corals. They can also be territorial.

Added a Black Sailfin Blenny to my reef tank and it’s been actively grazing on algae on the live rock. The fish is bold and active, and its black coloration stands out well. I did notice it occasionally nipping at a soft coral, so I’ve repositioned it. Overall, a great algae eater.

The fish arrived healthy and has been active since setup. It spends most of its time on the rock feeding. I’m happy with its role in keeping algae under control. A bit territorial with other small fish, but manageable in a well-planned tank.

It’s a striking fish with a unique appearance. I’ve seen it feeding on algae and it seems to enjoy the rock surfaces. However, it did show interest in a clam mantle, so I’ve kept a close eye on that area.
