Can Chocolate Gourami live with Opaline Gourami?
Caution — with care
Why
- Only a narrow water hardness overlap — keep both around 5 dGH.
- Opaline Gourami is semi-aggressive and may bully the peaceful Chocolate Gourami — give lots of space and cover.
- Opaline Gourami is large enough to threaten a small Chocolate Gourami — usually fine once both are adult, but watch new additions.
Sweet spot: both do well at 78–82°F and pH 6–6.5 — aim there.
