Common name: Breast-spot blenny

General information

The Jeweled Blenny, scientifically known as Salarias guttatus, is a distinctive and charming fish that adds both character and utility to a reef aquarium. Recognizable by its mottled pattern of brown and white spots, which gives it a jeweled appearance, this species is a member of the Blenniidae family. It is often found perching on rocks or coral, darting quickly to snatch up small bits of food.

Blennies from the genus Salarias are known for their algae-eating habits, making them a valuable addition to control unwanted algae growth in the tank. They are also known for their curious and bold behavior, often becoming a favorite among aquarists for their personality.

Care

Jeweled Blennies are hardy and adaptable, making them suitable for both novice and experienced aquarists. They thrive in well-established aquariums with plenty of live rock for grazing and hiding. While they primarily feed on algae, they will also accept a variety of prepared foods, such as frozen or dried marine algae, and foods designed for herbivorous fish.

A tank with a tightly fitting lid is recommended, as blennies are known to be skilled jumpers and may leap out of open aquariums. Providing a varied environment with both open swimming spaces and crevices will mimic their natural habitat and keep them engaged and healthy.

Reproduction

In the wild, Jeweled Blennies are oviparous, with males often guarding and aerating the eggs until they hatch. Breeding them in captivity can be challenging, and there are few reports of successful breeding in home aquariums. Hobbyists interested in breeding should provide a separate breeding tank with optimal conditions to increase the chances of success.

Habitat

Salarias guttatus is native to the Indo-Pacific region, where it is commonly found in shallow, reef-associated environments. They are often seen in tide pools and along rocky shorelines, where they can escape predators by jumping from pool to pool or hiding in crevices.
