Can Threestripe Cory live with Opaline Gourami?
Light caution
Why
- Opaline Gourami is large enough to threaten a small Threestripe Cory — usually fine once both are adult, but watch new additions.
- Opaline Gourami is semi-aggressive — give the peaceful Threestripe Cory plenty of space, cover and broken sight lines.
Sweet spot: both do well at 72–79°F and pH 6–7.5 — aim there.
