Can Noble Gourami live with Giant Gourami?
Not recommended
Why
- Giant Gourami’s mouth is big enough to swallow Noble Gourami (only 3" long) — it will be eaten.
- Noble Gourami and Giant Gourami are both labyrinth fish — they claim the same surface territory and will fight, especially between males.
- Only a narrow water hardness overlap — keep both around 6–7 dGH.
- Giant Gourami is semi-aggressive — give the peaceful Noble Gourami plenty of space, cover and broken sight lines.
