These vibrant and social freshwater fish are recognized for their distinct red "nose" markings and silver bodies. Part of the Characidae family, they are prized for their schooling behavior, making them a captivating addition to community aquariums. While detailed information on their genome and evolution line may be limited, their popularity among aquarists is attributed to their striking appearance and peaceful nature.
