The care below is neon tetra-level guidance from our species hub, sourced to Merck Veterinary Manual — Aquarium Fish: Husbandry and Diseases and RSPCA — Aquarium fish care advice.

How long do Neon Tetras live?

With stable, cycled water and a good diet, Neon Tetras live about 5-8 years, occasionally longer. Wild-caught specimens often already carry neon tetra disease, which shortens lifespan; tank-raised fish from a reputable source are the safer bet for a long-lived school.

What do Neon Tetras eat?

They have tiny mouths: feed crushed flake, micro-pellets, and small frozen or live foods like brine shrimp and daphnia, once or twice daily in portions finished in two minutes. The common mistake is feeding only one flake brand or overfeeding, which fouls the water and invites disease; vary the diet and keep it small.
