Care and Environment

Providing optimal care for the Head and Tail Light Tetra involves replicating its natural habitat and meeting its specific needs.

What is the minimum tank size for a Head and Tail Light Tetra?

A minimum tank size of 60 litres is recommended to accommodate a small group of these tetras, as they thrive in schools of six or more.

What are the ideal water parameters for Head and Tail Light Tetras?

Maintain a temperature between 22°C and 28°C, a pH level of 6.0 to 7.5, and water hardness between 5 to 20 dGH.

How should the tank be set up for Head and Tail Light Tetras?

Use a dark substrate to enhance their colors and provide plenty of live plants, such as Java Moss and Amazon Swords, to mimic their native habitat and offer hiding spots.

Ensure the tank has a gentle water flow, as these tetras prefer slow-moving waters. A quality filtration system is essential to maintain water quality, and regular water changes of 25-30% every 1-2 weeks are recommended.

Lighting should be subdued, with floating plants to diffuse bright light, creating a comfortable environment for the tetras.

As omnivores, Head and Tail Light Tetras accept a variety of foods. A balanced diet includes high-quality flake or pellet foods, supplemented with live or frozen options like brine shrimp, daphnia, and bloodworms. Feed them small portions 2-3 times daily, ensuring they consume the food within a few minutes to prevent overfeeding.

Origin and Habitat

Native to South America, the Head and Tail Light Tetra inhabits the Amazon River Basin, including regions in Brazil, Peru, and Suriname. They are typically found in slow-moving, densely vegetated rivers and streams. These environments are characterized by soft, slightly acidic water, abundant plant life, and a dark substrate, providing ample hiding spots and a rich supply of food sources.
