Behaviour
Hyphessobrycon Agulha is known to be very peaceful, making it an ideal addition to a well-researched community aquarium. It is recommended to keep them alongside similarly sized characids, gasteropelecids, lebiasinids, smaller callichthyid or loricariid catfishes, and non-predatory, small-to-medium-sized cichlids. To create a natural-looking spectacle, it is advised to purchase a mixed-sex group of at least 8-10 specimens and include other schooling fishes to provide security.
Feeding and Diet
Being likely omnivorous, the Hyphessobrycon Agulha feeds on small invertebrates, crustaceans, filamentous algae, fallen fruit, and other similar food sources in its natural habitat. In captivity, they can survive on a diet of dried foods but thrive best when offered a varied menu that includes live and frozen foods like chironomid larvae (bloodworms), mosquito larvae, Daphnia, and Moina.
Reproduction & Dimorphism
Information regarding the reproduction of Hyphessobrycon Agulha is unreported. However, sexually mature females are noted to be deeper-bodied and slightly larger than males. This sexual dimorphism helps in distinguishing between the genders of this species.
Habitat and Distribution
Hyphessobrycon Agulha is primarily found in the rio Madeira system, which is the largest tributary within the Amazon basin. Its range spans across Amazonas state in northwestern Brazil, parts of Rondônia state, Peru, and Bolivia. The species has been collected from tributaries near Porto Velho and the Madeira River. Records also mention sightings in the upper and lower Amazon regions in Peru and the ri0 Tapajós drainage, but these need further confirmation.
