Natural habitat

Neon Tetras inhabit the slow-moving waters of the Amazon Basin. They prefer dimly lit environments that are rich in vegetation and offer hiding spots.

Where they are found

Primarily located in South America, Neon Tetras are mainly found in the Amazon River and its tributaries, thriving in slightly acidic waters.

Aquarium care

Provide a well-planted aquarium with dark substrates to highlight their colors. Maintain stable water parameters, ensuring good filtration and regular water changes of at least 10% weekly. Use gentle currents and avoid direct sunlight to minimize stress.

Feeding

Feed Neon Tetras a varied diet including high-quality flakes, granules, and occasional live or frozen foods. They should be fed small amounts that can be consumed within a couple of minutes, twice a day.

Compatibility

Neon Tetras are best kept in schools of at least 6 individuals and can coexist peacefully with similarly sized fish. Ideal tank mates include other tetras, small rasboras, danios, and peaceful barbs.

Breeding

Breeding Neon Tetras can be challenging. The tank should be well-planted with fine-leaved plants. After spawning, parents should be removed to prevent them from eating the eggs. Eggs typically hatch within 24-36 hours.
