Chili Rasbora
Tiny soft-water schooling fish.
Planning your aquarium
The library starting point is 5+ US gallons. Plan for the approximate 0.8-inch adult size and the species' normal activity, not just its current shop size.
The library suggests a group of at least 8. 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.
- Favor naturally appropriate soft-water conditions rather than abrupt chemical adjustments.
Give a larger school dense planting, gentle flow and tiny foods.

Food and feeding

Use appropriately sized, complete staple foods and rotate suitable foods for variety. Feed modest portions and remove uneaten food.
Additional care caution
Keep away from fish large enough to swallow these very small rasboras.
Tankmate cautions in the checker
- Avoid or investigate Angelfish: Adult angelfish can treat tiny chili rasboras as prey.
- Avoid or investigate Electric Blue Acara: The size difference creates a significant predation risk.
- Avoid or investigate Oscar: Chili rasboras are prey-sized for an oscar.
- Avoid or investigate Golden Wonder Killifish: Chili rasboras are small enough to be eaten.
These are selected rule-based cautions, not a complete compatibility assessment.
