Cardinal Tetras boast a slender, elongated body adorned with striking longitudinal stripes. The bold red stripe runs along the lower body, flanked by a brilliant blue stripe on the upper side. Typically, they reach a size of about 2 inches (5 cm) when fully grown, making them a compact yet eye-catching addition to your aquarium.
Originating from the warm, soft, and slightly acidic waters of the Orinoco and Negro Rivers in South America, Cardinal Tetras thrive in well-planted environments. In the wild, they maneuver through dense vegetation and fallen leaves, a lifestyle that can be replicated in a home aquarium to keep them comfortable and healthy.
To mimic their natural habitat, a tank for Cardinal Tetras should have a temperature range of 73-81°F (23-27°C), a pH of 5.5 to 7.5, and soft to moderately hard water. Plentiful vegetation, a dark substrate, and subdued lighting will help recreate the peaceful and sheltered conditions of their native waters.
Cardinal Tetras are omnivorous by nature, feeding on a balanced diet of small insects, crustaceans, and plant matter in the wild. In the home aquarium, they will thrive on high-quality flake food, brine shrimp, and daphnia. Occasional treats of live or frozen foods will keep them in vibrant health.
Much like the peaceful coexistence of Red Cherry Shrimp with other tank mates, Cardinal Tetras are community-friendly fish. They get along well with other peaceful and similarly sized fish such as Harlequin Rasboras, Corydoras Catfish, and of course, the Red Cherry Shrimp. Their tranquil demeanor makes them a harmonious choice for a community aquarium.
Breeding Cardinal Tetras can be a rewarding experience for the dedicated hobbyist. With a well-prepared breeding tank mimicking their natural conditions, these tetras will spawn, laying their eggs among fine-leaved plants. Patience and a controlled environment are keys to successfully breeding and raising the fry.
By adhering to these tips, you can ensure a happy, healthy, and visually stunning habitat for your Cardinal Tetras, making your aquascaping endeavor a rewarding experience.
