Can King Tiger Pleco live with Pygmy Rasbora?
Caution — with care
Why
- Very different sizes (King Tiger Pleco 6" 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 5.5–7 dGH.
Sweet spot: both do well at 79–82°F and pH 6.5–7 — aim there.
