Salarias fasciatus – Lawnmower Blenny
The Lawnmower Blenny is a classic favorite for reef and marine tanks for their algae eating prowess. In addition to being a utility fish that helps maintain your tank, they also tend to have adorable personalities that endear them to their humans.
These fish are great for medium to large size aquariums needing an algae-eating fish. This species is generally quite peaceful with other fish species but can become aggressive toward fish with similar body shape, appearance, or diets, especially if they feel they don’t have enough territory.
Feeding
Captive bred Lawnmower Blennies are not picky when it comes to feeding and will take most aquarium foods. We recommend a varied diet including algae wafers, frozen foods, and small pieces of meaty foods to ensure balanced nutrition.

My reef tank has been much cleaner since I added the Lawnmower Blenny. It constantly grazes on algae and doesn’t seem to get bored. It’s active and friendly, and fits well in the tank without causing any issues.

The fish is hardy and easy to care for. I feed it a mix of algae wafers and frozen foods. It’s not aggressive with my other fish, though I did notice it became a bit territorial when another blenny was introduced.

Great addition to my marine tank. It’s small, active, and helps keep the glass clean. I appreciate how it doesn’t require special feeding and adapts well to the tank environment.
