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