Ruby Tetra (Axelrodia riesei)

Ruby Tetra, scientifically known as Axelrodia riesei, is a small and colorful freshwater fish admired for its vibrant red coloration, delicate appearance, and peaceful schooling behavior. Native to South America, this rare tetra is a popular choice among aquarists who enjoy keeping unique nano fish.

Ruby Tetra thrives in a planted aquarium with soft, slightly acidic water, gentle filtration, and plenty of swimming space. As a schooling species, it should be kept in groups to help reduce stress and encourage natural activity.

This peaceful tropical fish has a small size and is best suited for calm community aquariums with other gentle tank mates. A varied diet of high-quality micro foods, flakes, frozen foods, and small live foods helps maintain its bright colors and overall health.
