Behavior and Temperament
Peaceful Nature
The lawnmower blenny, also known as Salarias fasciatus, is a peaceful fish that many marine aquarists love due to its algae-eating habits. I’ve found that these fish tend to get along really well with others that share a similar temperament. Their friendly nature makes them a great addition to a community tank, especially if you’re looking to maintain a healthy reef environment. However, they have their quirks.
Territorial Tendencies
Despite their generally calm demeanor, lawnmower blennies can be territorial. It’s essential to keep in mind that they shouldn’t be housed with other blennies or fish that look like them; otherwise, you might witness some aggressive behavior. They can also be a bit nippy towards certain corals, like polyps and clams, which is why they aren’t considered 100% reef safe (FantaSEA Aquariums).
To help manage their territorial tendencies, I recommend introducing them into a well-established tank. This gives them plenty of space to explore, which can help reduce any signs of aggression. If you’re planning to add other fish, consider those that have distinct appearances to avoid conflicts.
