Common name: Bicolor rosefish

General information

The Bluelined Sabretooth Blenny, scientifically known as Sebastapistes cyanostigma, is a small and intriguing fish species popular among marine aquarists. This species is known for its distinctive blue lines that run along the sides of its body, which can add a splash of color to any aquarium. Despite its common name, it is not a true blenny but belongs to the family Scorpaenidae, which includes scorpionfish and lionfish.

One of the unique features of this species is its ability to deliver a venomous bite using its canine-like teeth, a defense mechanism against predators. However, this is rarely a concern for hobbyists as long as they handle the fish with care and avoid provoking it.

Care

The Bluelined Sabretooth Blenny requires a well-established aquarium with plenty of live rock for hiding and hunting. They are generally peaceful but can be territorial with their own kind or similar-looking species. It's important to provide a varied diet that includes meaty foods such as mysis shrimp, brine shrimp, and finely chopped seafood.

Reproduction

In the wild, Sebastapistes cyanostigma is oviparous, with females laying eggs that are then fertilized by the male. The eggs are adhesive and will attach to the substrate or decor within the tank. Breeding in captivity is not common, and there is limited information available on their reproductive habits in home aquariums.

Habitat

Bluelined Sabretooth Blennies are found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They prefer reef environments, often hiding in crevices and among coral rubble. They can be found at depths ranging from shallow waters to about 25 meters deep.
