Columbian tetra

Introduction

The Columbian tetra (Hyphessobrycon columbianus), also known as the blue-red Columbian tetra, is a vibrant freshwater fish cherished by aquarists for its striking coloration and active demeanor. With a shimmering silver-grey body accented by a turquoise-blue sheen and vivid red fins, this species adds a splash of color to any aquarium. Generally hardy and adaptable, Columbian tetras are suitable for both novice and experienced fishkeepers, provided their specific care requirements are met.

What makes the Columbian tetra a popular choice among aquarists?

Their captivating colors, energetic swimming patterns, and relatively straightforward care make them a favorite among hobbyists.

Are Columbian tetras suitable for beginners?

Yes, with proper tank conditions and compatible tank mates, they are well-suited for beginners.

Care and Environment

Proper care is essential to ensure the health and longevity of Columbian tetras. Below are key considerations for their optimal environment:

What is the minimum tank size for a Columbian tetra?

A minimum tank size of 75 liters is recommended to provide adequate swimming space and accommodate a small school of these active fish.

What are the ideal water parameters for Columbian tetras?

They thrive in temperatures between 24°C and 27°C, with a pH range of 6.0 to 7.0, and water hardness between 6° to 15° dH.

How should the tank be set up for Columbian tetras?

Incorporate live plants like Java fern and Anubias, along with driftwood and rocks, to create hiding spots and mimic their natural habitat. A dark substrate can enhance their vibrant colors.

What type of filtration and lighting do they require?

A filter that provides gentle to moderate flow is suitable, as they prefer slow-moving waters. Moderate lighting is ideal, especially if the tank is planted.

What should be included in their diet?

As omnivores, they should be fed high-quality flake or pellet food supplemented with live or frozen foods like brine shrimp, daphnia, and bloodworms.

Are there any specific challenges in keeping Columbian tetras?

They can exhibit fin-nipping behavior, especially if not kept in adequate group sizes. Maintaining water quality and providing a stress-free environment are crucial to prevent aggression.

Origin and Habitat

Columbian tetras are native to the Acandí River near Acandí in northwestern Colombia. They inhabit slow-moving creeks and tributaries characterized by dense vegetation and soft substrates. These environments typically have slightly acidic to neutral pH levels and warm temperatures, conditions that should be replicated in the home aquarium to ensure their well-being.

Where are Columbian tetras originally from?

They originate from the Acandí River in northwestern Colombia.

What type of natural habitat do they prefer?

They favor slow-moving creeks and tributaries with dense vegetation and soft substrates.

Temperament and Compatibility

Columbian tetras are generally peaceful but can display semi-aggressive tendencies, particularly towards smaller or long-finned tank mates. They are schooling fish and should be kept in groups of at least six to reduce stress and minimize aggressive behaviors. Suitable tank mates include other similarly sized tetras, rasboras, and peaceful barbs. It's advisable to avoid housing them with slow-moving or delicate fish that might become targets for fin-nipping.

Are Columbian tetras aggressive?

They can exhibit semi-aggressive behavior, especially if not kept in appropriate group sizes.

What are suitable tank mates for Columbian tetras?

Other similarly sized tetras, rasboras, and peaceful barbs are suitable companions.

Why is it important to keep them in groups?

Keeping them in groups of at least six reduces stress and minimizes aggressive behaviors.

Interesting Facts

Columbian tetras were only described scientifically in 2002, making them a relatively recent addition to the aquarium trade. They are known for their active swimming patterns and can often be seen darting around the tank, especially during feeding times. While they are egg scatterers and do not exhibit parental care, breeding them in captivity can be challenging due to specific water parameter requirements and the need for a separate breeding tank.

When were Columbian tetras scientifically described?

They were described in 2002.

Do Columbian tetras exhibit parental care?

No, they are egg scatterers and do not provide parental care.

Is breeding Columbian tetras in captivity easy?

Breeding can be challenging due to specific water parameter requirements and the need for a separate breeding tank.
