Species description
Geographical Origin and Habitat: Broadly distributed in the Paraná and Paraguay River basins, and parts of the Amazon. Inhabits shallow, slow-moving rivers, marshes, and flooded areas.
Taxonomy and Morphology: Classified in the Characidae family. Features an elongated body with an upturned mouth adapted for surface feeding.
Social Behavior: Very active schooling fish. Keeps well in groups of 6 or more, showing active, fast-paced swimming patterns near the surface.
Coloration and Sexual Dimorphism: Silvery-grey iridescent body, featuring red-orange fins and a bright golden-yellow spot on the tail base. Males are slimmer and more brightly colored.
Care, breeding and tankmates
Aquarium Setup: Long tank with plenty of open swimming space at the top. Secure lid is mandatory as they are highly prone to jumping.
Diet and Feeding: Omnivorous. Feeds near the water surface. Readily accepts floating flakes, pellets, and freeze-dried or frozen daphnia.
Water Quality: Highly adaptable to varying water conditions. Prefers a pH between 6.0-7.5 and temperature of 22-27°C.
Compatibility and Cohabitation: Peaceful community fish, best housed with other active species like barbs, danios, and bottom-dwelling catfish.
Aquarium Breeding: Oviparous. Disperses eggs in the water column; adult fish should be removed immediately after spawning.
Risks and Diseases: Very hardy. The main hazard is their jumping behavior when startled or during water changes.
