They are not the most colorful members of the family, but the color usually consists of bands, stripes, and spots in hues of brown, green, and cream. Their color patterns typically help them to disappear against the reef substrate.

Lawnmower Blenny Basics

Biology

  • The Salarias species are residents of tropical, shallow coastal habitats. They typically are found on fringing reefs or on lagoon patch reefs and rubble patches. These blennies regularly live among coral rubble, macroalgae, or branching stony corals or at the base of sponges. Salarias spp. are most often found at depths of less than 15 meters (50 feet). There is one newly describ…

The Jeweled Blenny: A Case Study

  • Salarias spp. spend most of their time in repose on hard substrates. When threatened, they dive into a crack or hole. While data is lacking for most species, at least one species has been studied in depth and is known to be territorial. This species, the jeweled blenny (S. fasciatus), has been studied in great detail on the reefs around Heron Island, Great Barrier Reef. (While it cannot be s…

Captive Care

  • Of the 13 species in the genus, one is common in the aquarium trade and several others make regular appearances in local fish stores. As mentioned above, the members of the genus Salarias are often employed to aid in the control of filamentous algae. In fact, S. fasciatus is one of the most popular algae-eating fishes. They are also fascinating to watch. They will dash from one lo…

Feeding Habits

  • Individuals vary in their usefulness in controlling some of the dreaded hair algae species. Some of the larger species (e.g., S. fasciatus) regularly consume filamentous algae. However, there are individual Salarias that tend to ignore it, choosing instead to rasp diatoms and other unicellular microalgae off the aquarium glass or live rock. It has ...

Tankmates

  • The best rule of thumb is to keep only one Salarias sp. per tank. They will definitely fight with members of their own kind and with other species in the genus. If your tank is larger, you can house a pair of conspecifics. You may even get away with keeping several congeners in the same tank if the aquarium is very large (e.g., 180 gallons or more). While disputes may occur along ter…
