Can Axelrod's Rasbora live with Tiger Barb?
Caution — with care
Why
- Very different sizes (Tiger Barb 2.75" vs Axelrod's Rasbora 0.6") — these two need different tanks, and the smaller fish will be out-competed at feeding time.
- Only a narrow water hardness overlap — keep both around 4–6 dGH.
- Tiger Barb is semi-aggressive — give the peaceful Axelrod's Rasbora plenty of space, cover and broken sight lines.
Sweet spot: both do well at 74–79°F and pH 6–6.5 — aim there.

How to make it work
- Target the overlapping water-parameter range and acclimate slowly.
- Use a larger, well-decorated tank with sightline breaks, keep everyone well-fed, and add the calmer fish first.
