The Ideal Number of Neon Tetras for a 20-Gallon Tank
So, how many Neon Tetras can be safely kept in a 20-gallon tank? The general rule of thumb is to keep 1-2 inches of fish per gallon of water. Based on this guideline, a 20-gallon tank can support 20-40 inches of fish.

- Filtration and water quality: A well-maintained tank with excellent filtration and water quality can support more fish than a tank with subpar conditions.
- Other tank inhabitants: If you plan to keep other fish or invertebrates in the tank, you’ll need to factor in their space and resource requirements.
- Feeding and nutrition: Overfeeding can lead to water quality issues, so it’s essential to ensure you’re not overstocking your tank.
