Can Tail Spot Pygmy Cory live with Opaline Gourami?
Not recommended
Why
- Opaline Gourami’s mouth is big enough to swallow Tail Spot Pygmy Cory (only 1" long) — it will be eaten.
- Only a narrow water hardness overlap — keep both around 6–7.5 dGH.
- Opaline Gourami is semi-aggressive — give the peaceful Tail Spot Pygmy Cory plenty of space, cover and broken sight lines.
