Lawnmower Blenny Md

About this fish

Lawnmower Blenny Md is a saltwater blenny sold as Salarias fasciatus for the home aquarium. It’s a popular addition for aquarists who enjoy active, personable fish that frequently explore and perch on rockwork. In practical use, it can help graze algae from the rocks, especially in a mature tank where natural growth is present, and it can be paired with supplemental foods to support overall condition.

Features:

• Grazer-style feeding behavior: it spends time picking at algae on live rock surfaces
• Often shows lots of personality, including perching and watching tank activity
• Generally peaceful toward other fish, making it a good option for community setups
• Best results come from a mature tank with visible natural algae growth
• Provide algae sheets and frozen foods alongside grazing to help maintain a balanced diet
• Include plenty of rockwork and hiding holes; acclimate slowly and allow a quiet settling-in period
• When possible, keep only one of a kind unless your tank is large
