Can Emerald Dwarf Rasbora live with Tiger Barb?
Light caution
Why
- Tiger Barb is semi-aggressive — give the peaceful Emerald Dwarf Rasbora plenty of space, cover and broken sight lines.
- Large size gap (Tiger Barb 2.75" vs Emerald Dwarf Rasbora 0.9") — watch that the smaller one gets its share at feeding time.
Sweet spot: both do well at 74–77°F and pH 7–8 — aim there.
