Can Brilliant Rasbora live with Axelrod's Rasbora?
Caution — with care
Why
- Very different sizes (Brilliant Rasbora 4" 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.
Sweet spot: both do well at 72–79°F and pH 5.5–6.5 — aim there.
