One of the Combtooth blennies, the Lawnmower Blenny's teeth are combed which gives them that "mowing" ability. They are great at scraping algae off of the rocks.
This fish has a typical blenny shape, a body that is long and slender with one long dorsal fin extending the length of the body. It will sit on the bottom of the aquarium with a curved stance. Typical coloring is a gray or tan background with darker streaks and bands, and small blue and black spots on the head. The head is blunt with the eyes perched up high on the head, and they have what looks like delicate tufts of hair called 'cirri' around the face.
The Lawnmower Blenny's appearance gives it an adorable charm to go along with a great personality. This along with algae being its prime food source, make this fish an excellent addition to a peaceful reef aquarium.

Maintenance difficulty: The Lawnmower Blenny is easy to keep if provided the right environment with plenty of algae. They are ideal for a large reef environment. Provide plenty of caves and hiding places.
Maintenance/Foods: This fish is a primarily an algae eater, munching on the microalgae that grows in your aquarium (varieties of hair and string algae). This along with commercially prepared herbivore foods such as marine and spirulina algae will provide a suitable diet.
Social Behaviors: This blenny is generally peaceful with other fish, with a possible exception being its own kind and other similar blennies. It is best kept singly, or possibly as a male/female pair.
Sex: Sexual differences: Both male and female blennies have two spines in the anal fin. In the female one or both may be smaller or even embedded while on the male they may be capped with a fleshy tissue.
Breeding/Reproduction: We have found no information at this time on breeding the Lawnmower Blenny (2/21/06). However it is known that some blennies lay demersal eggs that are guarded by the male.
