Can Giant Gourami live with Moonlight Gourami?
Caution — with care
Why
- Giant Gourami may eat Moonlight Gourami; add only full-grown adults, because juveniles and fry will be picked off.
- Only a narrow water hardness overlap — keep both around 6–7.5 dGH.
- Giant Gourami is semi-aggressive and may bully the peaceful Moonlight Gourami — give lots of space and cover.
Sweet spot: both do well at 77–82°F and pH 6.5–7.6 — aim there.

How to make it work
- Add only full-grown adults — never juveniles, which will be eaten.
- Target the overlapping water-parameter range and acclimate slowly.
- Use a larger, well-decorated tank with sightline breaks, keep everyone well-fed, and add the calmer fish first.
