Can Giant Gourami live with Siamese Algae Eater?
Caution — with care
Why
- Giant Gourami may eat Siamese Algae Eater; 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 — give the peaceful Siamese Algae Eater plenty of space, cover and broken sight lines.
Sweet spot: both do well at 72–79°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.
