Can Opaline Gourami live with False Rummynose Tetra?
Caution — with care
Why
- Opaline Gourami is semi-aggressive and may bully the peaceful False Rummynose Tetra — give lots of space and cover.
- Opaline Gourami is large enough to threaten a small False Rummynose Tetra — usually fine once both are adult, but watch new additions.
Sweet spot: both do well at 75–82°F and pH 6–7 — aim there.
