Can Green Tiger Barb live with Axelrod's Rasbora?
Caution — with care
Why
- Very different sizes (Green 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.
- Green 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.
