Common name: White-line seawhip goby

General information

The Loki Whip Coral Goby, Bryaninops loki, is a small and fascinating fish species that is well-suited for nano and small reef aquariums. This species is named after the Norse god Loki, likely due to its elusive nature and the intricate patterns on its body that may remind one of the trickster god's shapeshifting abilities. They are known for their slender bodies and their ability to blend into their surroundings, making them a delightful challenge to spot in a well-structured reef tank.

Care

Loki Whip Coral Gobies are peaceful and can be kept with other non-aggressive tank mates. They require a mature aquarium with plenty of live rock and hiding places. These gobies are not demanding when it comes to feeding; they will readily accept a variety of small meaty foods such as brine shrimp, copepods, and finely chopped seafood. Care should be taken to ensure that these small fish are not outcompeted for food by larger, more aggressive tank mates.

Reproduction

Little is known about the breeding habits of Bryaninops loki in the home aquarium. However, like many other goby species, they are likely to spawn in a secure cave or crevice, with the male guarding the eggs until they hatch.

Symbiosis

Bryaninops loki has a commensal relationship with certain species of whip corals, such as those in the genus Cirrhipathes. They use these corals as both a habitat and a hunting ground, picking off small food particles that drift by. This relationship benefits the gobies without harming the corals, making it a fascinating example of marine symbiosis to observe in a reef tank.

Habitat

Loki Whip Coral Gobies are found in the Indo-Pacific region, typically in coral reefs and lagoons. They are often associated with whip corals at various depths, which provide them with shelter and a place to feed.
