Can Giant Gourami live with Thick-lipped Gourami?
Not recommended
Why
- Giant Gourami’s mouth is big enough to swallow Thick-lipped Gourami (only 3.5" long) — it will be eaten.
- Giant Gourami and Thick-lipped 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 6–7.5 dGH.
- Giant Gourami is semi-aggressive — give the peaceful Thick-lipped Gourami plenty of space, cover and broken sight lines.
