General information

The Red Sea Hovering Goby, scientifically known as Bryaninops natans, is a small and fascinating marine fish that is well-suited for nano and small reef aquariums. This species is known for its unique behavior of hovering in the water column, often near the branches of soft corals or gorgonians. They are a transparent fish with a slender body and a distinctive red line running from the snout through the eye to the base of the caudal fin, which adds a subtle splash of color to their appearance.

Care

Bryaninops natans is a peaceful fish that does well in a mature aquarium with plenty of live rock and soft coral growth. They prefer aquariums with gentle water flow and low to moderate lighting. Due to their small size and timid nature, they should be kept with other non-aggressive tank mates. A varied diet of small, meaty foods such as copepods, brine shrimp, and finely chopped seafood is essential for their health.

Reproduction

Little is known about the breeding habits of the Red Sea Hovering Goby in the wild or in captivity. However, like many other gobies, they are likely to form monogamous pairs and spawn in a secure location within the aquarium.

Symbiosis

While not involved in a symbiotic relationship as intimate as clownfish and anemones, Bryaninops natans often associates with soft corals and gorgonians. They use these structures as a place to hover and seek refuge from potential predators, as well as a platform from which to catch passing prey.

Habitat

The natural habitat of the Red Sea Hovering Goby is the coral reefs of the Red Sea. They are typically found at depths ranging from shallow waters to about 40 meters, where they associate with branching soft corals and gorgonians.
