Buenos Aires Tetra
The tetra is a tropical, silver metallic-colored fish, with red-tipped fins and a black marking on the dorsal fin. The tetra is a hardy community fish for beginners, and is optimal for the beginning fish hobbyist. It is also relatively large for a tetra, growing up to 7.5 cm (3 inches). They can live up to 5 or 6 years. Its silver color picks up flashy neon highlights depending on how the light hits the fish. The top and bottom of the tail fin is generally red, along with the pelvic and anal fins. The dorsal fin may also have a hint of red at the very tip. Its most distinguishing characteristic is the caudal peduncle, or the connecting area between the tail and the rest of the body, which features a bold, black 'cross' shape.
Buenos Aires tetras are an omnivorous species. In the wild they feed on worms, crustaceans, insects, and plants, but in the aquarium they will generally eat all kinds of live, fresh, and flake foods. To keep a good balance, give them a high quality flake food every day. To keep these tetras at their best and most colorful, offer regular meals of live and frozen foods, such as bloodworms, daphnia, and brine shrimp. Vegetables should also be added to their diet. Feed these tetras several times a day and only what they can consume in 3 minutes or less at each feeding.
