• Coloration: The Columbian Tetra boasts a silvery-blue body with a red-tinted tail, adding a splash of color to any aquarium setting. The iridescent hues can vary slightly among individuals but remain consistently eye-catching.
• Size: Typically, Columbian Tetras reach an average length of 2.5 to 3 inches (6.4 to 7.6 centimeters) when fully grown, making them a moderately sized fish for community tanks.
• Body Shape: Their streamlined, laterally compressed bodies allow them to navigate swiftly in their natural habitat as well as in captivity, enhancing their compatibility with various tank setups.

Distinctive Behaviors

One of the most entertaining aspects of keeping Columbian Tetras is their lively behavior:

• Active Swimmers: These tetras are known for their vigorous swimming patterns, often darting energetically across the tank. Their activity level can increase during feeding times or when interacting with fellow tank mates.
• Playful Interactions: Observing Columbian Tetras engage in playful chases or group swimming can be an engaging experience for fish keepers.

Understanding the Natural Habitat of the Columbian Tetra

Origin and Distribution

The Columbian Tetra is native to the warm and tropical freshwater environments of South America:

• Geographic Range: Primarily found in the wild along the rivers of Colombia, these tetras inhabit slow-moving water bodies with dense vegetation.
• Climate: The natural environment offers warm temperatures, ranging from 75 to 82 degrees Fahrenheit (24 to 28 degrees Celsius), with slightly acidic to neutral pH levels.

In replicating these conditions, aquarists can ensure the health and longevity of Columbian Tetras in captivity.

Ideal Aquarium Setup

Creating a tank that mimics the Columbian Tetra's natural habitat is crucial for maintaining their well-being:

• Tank Size: A minimum of 20 gallons is recommended for housing a small school. Larger tanks are better to accommodate their active nature and reduce territorial aggression.
• Water Conditions: Maintaining a stable temperature between 75 and 80 degrees Fahrenheit (24 to 27 degrees Celsius) and a pH range of 6.0 to 7.5 is ideal.
• Lighting: Moderate lighting conditions, paired with densely planted areas, mimic their natural habitat and provide hiding spots, which are appreciated during rest.
• Substrate and Decor: Sandy or fine gravel substrates with driftwood and plant cover replicate their natural environment, encouraging natural behaviors.

Building a Community Tank with Columbian Tetras

Compatible Tank Mates

The Columbian Tetra's active nature and peaceful demeanor make them suitable for community tanks with other compatible species:

• Recommended Companions: Similar-sized tetras, rasboras, plecos, and corydoras catfish are among the best tank mates, as they share similar habitat needs and non-aggressive behavior.
• Avoid Aggressive Species: Larger, more aggressive fish should be avoided as they can cause stress or harm to the tetras.

Breeding Considerations

Breeding Columbian Tetras requires careful planning and specific conditions:

• Spawning Setup: A separate breeding tank with fine-leaved plants provides a suitable environment for spawning.
• Behavioral Cues: Males exhibit vibrant colors and perform courting displays during the breeding season, indicating readiness to mate.
• Raising Fry: After egg-laying, removing adult fish prevents predation on the eggs. Once hatched, fry can be fed infusoria or specially formulated fry food.
