Columbian Tetra: A Comprehensive Guide to Care and Keeping

Columbian tetras (Hyphessobrycon columbianus) are vibrant and active freshwater fish known for their striking orange-red fins and silver bodies. Native to the Acandi River in Colombia, these tetras are a popular choice for community aquariums due to their peaceful nature and relatively easy care requirements. Understanding their specific needs is crucial for ensuring their health and longevity in your home aquarium.

Appearance and Characteristics

Columbian tetras typically reach a size of around 2-3 inches (5-7.5 cm). Their most distinguishing feature is their bright orange-red fins, contrasting sharply with their silver or bluish body. A dark blotch often appears near the tail fin. These fish are active swimmers, adding a lively dynamic to any aquarium setting. They exhibit schooling behavior, meaning they thrive best in groups of six or more individuals.

Aquarium Setup and Water Parameters

To properly house Columbian tetras, a tank of at least 20 gallons is recommended for a small school. The aquarium should be well-planted, offering plenty of hiding places, but also providing open swimming space. Driftwood and rocks can also be used to create a natural and stimulating environment. Water parameters are crucial; these tetras prefer slightly acidic to neutral water with a pH of 6.0 to 7.5. The water temperature should be maintained between 72°F and 82°F (22°C to 28°C). Regular water changes (25% weekly) are essential to maintain optimal water quality. You can find more information about tetra fish including Columbian tetras on Wikipedia.

Diet and Feeding

Columbian tetras are omnivores and readily accept a variety of foods. A balanced diet consisting of high-quality flake food, supplemented with live or frozen foods such as bloodworms, daphnia, and brine shrimp, will keep them healthy and vibrant. Feed them small portions 2-3 times a day, only what they can consume in a few minutes.

Tank Mates

Columbian tetras are generally peaceful and get along well with other similarly sized, non-aggressive fish. Good tank mates include other types of tetras, rasboras, corydoras catfish, and peaceful dwarf cichlids. Avoid housing them with larger, predatory fish or fin-nipping species, as they can become stressed or injured.

Breeding

Breeding Columbian tetras in a home aquarium can be challenging. They are egg-scatterers and do not provide parental care. A separate breeding tank with soft, slightly acidic water is necessary. Provide fine-leaved plants or a spawning mop for the fish to lay their eggs on. After spawning, the parents should be removed to prevent them from eating the eggs. The fry will hatch in about 24-36 hours and can be fed infusoria or liquid fry food initially.

Common Health Issues

Columbian tetras are generally hardy, but they can be susceptible to common freshwater fish diseases, such as ich (white spot disease) and fin rot. Maintaining good water quality and providing a balanced diet are crucial for preventing these issues. If you notice any signs of illness, such as white spots, clamped fins, or lethargy, quarantine the affected fish and treat them with appropriate medication.
