Neon Tetra
Popular schooling fish for planted community tanks.
Planning your aquarium
The library starting point is 10+ US gallons. Plan for the approximate 1.5-inch adult size and the species' normal activity, not just its current shop size.
The library suggests a group of at least 6. Count every individual when estimating stocking and swimming room.
Mixed-species aquariums may need substantially more space. Tank length, adult behavior, filtration, and hiding spaces all matter.
Tank setup and behavior
- Include planting or cover without removing all open swimming space.
Keep a substantial group, calm planting around the edges and an open area for the school.

Food and feeding
Food options: Micro pellets, Fine flakes, Daphnia.
Use appropriately sized, complete staple foods and rotate suitable foods for variety. Feed modest portions and remove uneaten food.
Additional care caution
Very large tankmates may eat small tetras even when water parameters overlap.
Tankmate cautions in the checker
- Avoid or investigate Oscar: Neon tetras are small enough to be eaten by an oscar.
These are selected rule-based cautions, not a complete compatibility assessment.
