General Description
Rhaphiodon vulpinus, commonly known as Biara, is the sole member of its genus and is categorized under the order Characiformes. It is characterized by its elongated body, distinct dorsal fin placement, and the possession of 62-68 vertebrae. The species, often referred to as the "vampire barracuda," exhibits notable predatory behavior and is known for its needle-like teeth.
Aquarium Setup
The ideal tank setup for Rhaphiodon vulpinus mimics flowing streams or rivers, featuring a substrate of rocks, sand, and gravel, with ample swimming space. Decorate the aquarium with driftwood, roots, and branches while ensuring high oxygen levels and moderate water movement. To thrive, this species necessitates clean water, regular water changes, and a secure, tight-fitting lid due to its jumping tendencies.
Behaviour
Rhaphiodon vulpinus is best housed alone or with similarly-sized, non-aggressive fish that it cannot consume. While peaceful, it can be easily dominated and is recommended to be kept in groups in adequately sized aquariums. Individual specimens may display skittish behavior, especially in confined spaces.
Feeding and Diet
As an obligate piscivore, R. vulpinus primarily preys on live fish, transitioning to dead alternatives over time. Avoid feeding mammalian or avian meat and refrain from using feeder fish to minimize disease risks. A varied diet is essential to meet the nutritional needs of this predatory species.
Reproduction & Dimorphism
Reproductively active between September to April, R. vulpinus follows a seasonal reproductive strategy tied to the flood cycles of its natural habitat. Unlike some aquarium species, successful breeding of this fish in captivity has not been documented.
Habitat and Distribution
The distribution of Rhaphiodon vulpinus spans the Amazon basin, including regions in Peru, Brazil, Venezuela, Guyana, Paraguay, Uruguay, and Argentina. This species occupies main river channels and reservoirs, with fluvial populations undergoing yearly reproductive migrations across its range.
Etymology
The genus name Rhaphiodon stems from the Greek words for "needle" and "tooth," while the species name vulpinus originates from the Latin term for "fox."
