Can Chocolate Gourami live with Giant Gourami?
Not recommended
Why
- Giant Gourami’s mouth is big enough to swallow Chocolate Gourami (only 2" long) — it will be eaten.
- Chocolate Gourami and Giant Gourami are both labyrinth fish — they claim the same surface territory and will fight, especially between males.
- Only a narrow pH overlap — keep both around 6.5–6.5.
- Only a narrow water hardness overlap — keep both around 5–5 dGH.
- Giant Gourami is semi-aggressive — give the peaceful Chocolate Gourami plenty of space, cover and broken sight lines.
