Common name: Filament-finned prawn-goby

General information

The Hi Fin Red Banded Goby, scientifically known as Stonogobiops nematodes, is a small and attractive fish that is popular in the saltwater aquarium hobby. This species is known for its striking coloration, with a white body accented by red bands and a tall dorsal fin. It is a peaceful fish that can be a great addition to small and nano reef tanks.

Care

The Hi Fin Red Banded Goby is a hardy species that requires a tank with plenty of live rock for hiding and hunting for food. They are bottom dwellers and prefer a sandy substrate. This goby is known to jump, so a tight-fitting lid is essential to prevent escape. They accept a variety of foods including frozen mysis shrimp, brine shrimp, and quality pellet and flake foods.

Reproduction

In the aquarium, Stonogobiops nematodes may form monogamous pairs and spawn. The male typically guards the eggs until they hatch. Breeding this species in captivity can be challenging but rewarding for experienced hobbyists.

Symbiosis

One of the most fascinating aspects of the Hi Fin Red Banded Goby is its symbiotic relationship with certain species of pistol shrimp, particularly those in the genus Alpheus. The shrimp and goby share a burrow and maintain a mutualistic relationship: the shrimp digs and maintains the burrow while the goby stands guard against predators. The goby's keen eyesight complements the shrimp's digging ability, and they communicate through a series of tactile signals.

Habitat

Stonogobiops nematodes is found in the Western Pacific, from Indonesia to the Great Barrier Reef. They inhabit coral reefs and rubble slopes, typically at depths of 1 to 30 meters.
