Can Noble Gourami live with Oscar?
Not recommended
Why
- Oscar’s mouth is big enough to swallow Noble Gourami (only 3" long) — it will be eaten.
- Oscar is aggressive and will attack the peaceful Noble Gourami.
- Only a narrow temperature overlap — keep both around 74–75°F.
- Only a narrow water hardness overlap — keep both around 6–7 dGH.
