I think the asian leaf fish is "nandus nebulosus" is a different fish, that's even less active. It wouldn't be called a leaf fish if it didn't act like a leaf.
I was hoping that nandus nandus would be a bit more active that the regular leaf fishes.
They usually go for $5. I have kept nandus nandus and slaty blue nandus with datnoids and had no problems. They will take dried foods like pellets(floating or sinking) and are a little more on the shy side.
