Can Least Rasbora live with Tiger Barb?
Light caution
Why
- Tiger Barb is semi-aggressive — give the peaceful Least Rasbora plenty of space, cover and broken sight lines.
- Large size gap (Tiger Barb 2.75" vs Least Rasbora 0.8") — watch that the smaller one gets its share at feeding time.
Sweet spot: both do well at 75–82°F and pH 6–7 — aim there.
