Columbian Tetra: A Comprehensive Guide

The Columbian tetra (Hyphessobrycon columbianus) is a vibrant and active freshwater fish prized by aquarists for its iridescent blue and orange coloration. Native to the Acandi River basin in Colombia, these tetras bring a splash of color to any community aquarium. Their relatively peaceful nature and ease of care make them suitable for both beginner and experienced fish keepers.

Appearance and Characteristics

Columbian tetras are easily recognizable by their distinctive coloring. Their bodies exhibit a bright, shimmering blue-silver sheen, particularly along the sides. The fins, especially the caudal fin (tail), are a striking orange-red color, adding to their visual appeal. Males are generally more vibrant in color and slightly more slender than females. They typically reach a size of around 2-2.5 inches (5-6 cm).

Natural Habitat and Tank Setup

In the wild, Columbian tetras inhabit clear, slow-moving rivers and streams. Replicating this environment in an aquarium is key to their well-being. A minimum tank size of 20 gallons is recommended for a small school of 6-8 tetras. The aquarium should be well-planted with dense vegetation to provide hiding places and mimic their natural habitat. A dark substrate and subdued lighting will help to enhance their colors and reduce stress. Maintain a water temperature between 72-78°F (22-26°C), a pH level of 6.0-7.5, and ensure good water quality through regular water changes and filtration. You can find more information about Columbian Tetra on Wikipedia.

Diet and Feeding

Columbian tetras are omnivores and readily accept a variety of foods. A balanced diet should consist of high-quality flake food supplemented with live or frozen foods such as bloodworms, daphnia, and brine shrimp. Feed them small amounts 2-3 times a day, ensuring they can consume the food within a few minutes. Avoid overfeeding, as this can lead to water quality issues.

Tank Mates and Compatibility

Columbian tetras are peaceful fish that thrive in a community setting. They should be kept in schools of at least 6 individuals to reduce stress and encourage natural behaviors. Suitable tank mates include other peaceful tetras, rasboras, corydoras catfish, and small gouramis. Avoid housing them with larger, aggressive fish that may bully or prey on them.

Breeding

Breeding Columbian tetras in captivity can be challenging but not impossible. A separate breeding tank with soft, slightly acidic water and fine-leaved plants is recommended. Condition the breeding pair with live foods and introduce them to the breeding tank. The female will scatter eggs among the plants, and the parents should be removed after spawning to prevent them from eating the eggs. The eggs will hatch in about 24-36 hours, and the fry can be fed infusoria or liquid fry food until they are large enough to accept baby brine shrimp.

Common Problems and Diseases

Columbian tetras are generally hardy fish, but they are susceptible to common aquarium diseases such as ich (white spot disease) and fin rot. Maintaining good water quality, providing a balanced diet, and avoiding stress are essential for preventing these issues. If a fish shows signs of illness, isolate it in a quarantine tank and treat it with appropriate medication.

They are omnivores and eat a varied diet of flake food, frozen food, and live food.

Are Columbian Tetras easy to care for?

Yes, they are relatively easy to care for, making them suitable for beginner aquarists, as long as their basic needs are met (clean water, proper diet, adequate space).

Summary

Columbian tetras are a beautiful and relatively easy-to-care-for addition to any community aquarium. Their vibrant colors, peaceful nature, and active behavior make them a popular choice among fish keepers.
