Can Cherry Barb live with Opaline Gourami?
Light caution
Why
- Opaline Gourami is large enough to threaten a small Cherry Barb — usually fine once both are adult, but watch new additions.
- Opaline Gourami is semi-aggressive — give the peaceful Cherry Barb plenty of space, cover and broken sight lines.
Sweet spot: both do well at 73–81°F and pH 6–7.5 — aim there.
