Expert Care Tips for Neon Tetra
- Nano tank suitable: Neon Tetra can thrive in smaller tanks (10+ gal), but skip the bowl — even small fish need filtration and a heater.
- Cool-water species: Neon Tetra tolerates temperatures as low as 68°F. In most homes, no heater is needed, but watch for summer overheating above 77°F.
- Adaptable pH range: Neon Tetra accepts pH 5.5–7.0. Most tap water falls within this range, but always test and acclimate slowly.
- Peaceful community fish: Neon Tetra works well in community tanks. Still, avoid housing with fish large enough to eat them — a 1.2" fish is vulnerable to anything with a mouth bigger than 2×.
- Acclimation: Always drip-acclimate Neon Tetra over 30–45 minutes. Match temperature and pH gradually to prevent osmotic shock.
