Natural habitat

Green neon tetras inhabit slow-moving waters with soft, slightly acidic conditions found around the Orinoco and Negro rivers in South America. They thrive in dense vegetation and shades created by overhanging plants and driftwood, absorbing natural colors from the habitat.

Where they are found

Native to the Amazon basin in South America, this species inhabits areas with soft, slightly acidic waters. They are commonly found in forested streams where vegetation provides shelter and breeding grounds.

Aquarium care

To keep Green Neon Tetras happy, provide them with a heavily planted aquarium featuring dim lighting and ample hiding spaces. A gentle filter is ideal to mimic their natural slow-flowing habitat, and maintaining a well-structured environment encourages their vibrant colors to shine through.

Feeding

Feed them a balanced diet of high-quality flake or micro pellet foods to ensure proper nutrition. Supplement with occasional live or frozen foods like baby brine shrimp or daphnia to bring out their colors.

Compatibility

Green Neon Tetras are peaceful community fish. Ideal tank mates include other small, non-aggressive species and bottom dwellers like Corydoras catfish. However, avoid keeping them with large or aggressive fish that could pose a threat.

Breeding

Breeding Green Neon Tetras can be achieved in a separate breeding tank that features soft and slightly acidic water. Fine-leaved plants should be provided for spawning, and it's best to introduce pairs in the evening, as these fish are more likely to breed in dim light.
