Can Opaline Gourami live with Colombian Zebra Pleco?
Light caution
Why
- Only a narrow water hardness overlap — keep both around 6–7.5 dGH.
- Opaline Gourami is semi-aggressive — give the peaceful Colombian Zebra Pleco plenty of space, cover and broken sight lines.
Sweet spot: both do well at 77–82°F and pH 6.5–7.6 — aim there.
