Native Habitat and Species Information
Segmented Sailfin Blenny native habitat, distribution, behavior & aquarium compatibility.
The Segmented Sailfin Blenny, also commonly referred to as the Segmented Blenny, has a wonderful and inquisitive personality and will often be seen perched on rock or coral, just watching what's going on, which is often the same scenario when found within its natural habitat throughout the Indo-Pacific reefs. Segmented Sailfin Blennies have bushy cirri (whisker-like appendages) protruding from between the eyes and are equipped with combed teeth that are well suited for munching on marine algae.
Segmented Sailfin Blennies are named for their unique coloration and markings, which give them the appearance of having a body that is divided into multiple segments. Segmented Sailfin Blennies are an attractive species that display several different colors, from tan to yellow as well as dark brown to red hues, splotches, and markings. Segmented Sailfin Blennies are relatively peaceful, but they may conflict with their own kind as well as heterospecific species of a similar appearance. Segmented Sailfin Blennies are growing in popularity and are usually readily available within the hobby.
How to successfully keep Segmented Sailfin Blenny in the home aquarium.
The Segmented Sailfin Blenny should be provided with an established aquarium of at least 30 gallons with a sandy substrate as well as plenty of live rock for grazing, perching, and refuge. Many blenny species are known to be jumpers when startled and their aquarium environment should be equipped with a sealed top or a tight fitting hood in order to help prevent escape.
They prefer stable water conditions and their aquarium should be equipped with efficient, biological and mechanical filtration in addition to the use of a protein skimmer to help keep chemistry levels in check. Segmented Sailfin Blennies are a peaceful and overall reef-safe species, but they should not be kept with conspecifics, overly aggressive species, or fish of a similar appearance. They can sometimes nip at Acropora and SPS coral species.
Feeding & Nutrition
How to feed and provide proper nutrition for Segmented Sailfin Blenny.
Segmented Sailfin Blennies are herbivores that naturally prefer to graze on marine algae in the wild. In the aquarium they will graze on existing marine algae, but they should also be supplied with a variety of live or prepared marine algae, vegetable matter, and high-quality, Spirulina-based, prepared foods for herbivores (including flakes and pellets). Feed twice per day, but only what they consume within a few minutes.
