Can Bolivian Ram live with Pygmy Rasbora?
Caution — with care
Why
- Very different sizes (Bolivian Ram 3.5" vs Pygmy Rasbora 0.8") — 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 6–8 dGH.
Sweet spot: both do well at 75–79°F and pH 6–7 — aim there.
