Can Kribensis live with Pygmy Rasbora?
Caution — with care
Why
- Very different sizes (Kribensis 3.5" vs Pygmy Rasbora 0.8") — these two need different tanks, and the smaller fish will be out-competed at feeding time.
- Kribensis is semi-aggressive — give the peaceful Pygmy Rasbora plenty of space, cover and broken sight lines.
Sweet spot: both do well at 75–82°F and pH 6–7 — aim there.
