Description
Roeboides affinis is a predatory characin from South America, characterized by its silvery body and often a dark spot on its flank. It possesses sharp teeth adapted for its carnivorous diet, preying on smaller fish and invertebrates. This active species requires a spacious aquarium and careful consideration of tankmates due to its semi-aggressive temperament.
