Can Tail Spot Pygmy Cory live with Oscar?
Not recommended
Why
- Oscar’s mouth is big enough to swallow Tail Spot Pygmy Cory (only 1" long) — it will be eaten.
- Oscar is aggressive and will attack the peaceful Tail Spot Pygmy Cory.
- Only a narrow water hardness overlap — keep both around 6–7.5 dGH.
