Can Thick-lipped Gourami live with Oscar?
Not recommended
Why
- Oscar’s mouth is big enough to swallow Thick-lipped Gourami (only 3.5" long) — it will be eaten.
- Oscar is aggressive and will attack the peaceful Thick-lipped Gourami.
- Only a narrow water hardness overlap — keep both around 6–7.5 dGH.
