Care and Environment
Providing optimal care for Red Eye Tetras involves attention to tank size, water parameters, and environmental enrichment.
What is the minimum tank size for a single Red Eye Tetra?
A minimum tank size of 57 liters (15 gallons) is recommended for a small group of Red Eye Tetras, as they are schooling fish and thrive in groups.
What are the ideal water parameters for Red Eye Tetras?
Maintain a temperature between 22°C and 28°C (72°F to 82°F), a pH range of 5.5 to 8.5, and water hardness between 2 to 30 dGH.
How should the tank be decorated to suit Red Eye Tetras?
Incorporate live plants, driftwood, and rocks to mimic their natural habitat, providing hiding spots and open swimming areas.
Regular water changes of 25% to 50% every two weeks are essential to maintain water quality. A gentle filtration system is recommended to avoid strong currents, as Red Eye Tetras prefer calm waters. Feeding should include a balanced diet of high-quality flakes or pellets, supplemented with live or frozen foods like brine shrimp or bloodworms, and occasional vegetable matter such as blanched spinach.
Origin and Habitat
Red Eye Tetras are native to South America, specifically found in regions of Bolivia, Brazil, Paraguay, and Peru. They inhabit clear rivers and streams, often in areas with dense vegetation and slow-moving waters. These environments provide ample hiding spots and a rich ecosystem, which is beneficial for their survival and reproduction.
What type of water bodies do Red Eye Tetras naturally inhabit?
They are typically found in clear rivers and streams with slow-moving currents and dense vegetation.

Temperament and Compatibility
Red Eye Tetras are peaceful, schooling fish that thrive in groups of six or more. They are generally compatible with other non-aggressive species of similar size.
Are Red Eye Tetras suitable for community tanks?
Yes, they coexist well with other peaceful fish such as other tetras, rainbowfish, barbs, danios, and larger rasboras.
Do Red Eye Tetras exhibit any aggressive behaviors?
While typically peaceful, they may occasionally nip at the fins of slow-moving, long-finned fish, especially if not kept in adequate group sizes.
To create a harmonious tank community, avoid housing them with aggressive or significantly larger species that may intimidate or prey on them. Providing ample space and maintaining a well-structured environment with hiding spots can help mitigate potential stress and aggression.
