Will Clown Knifefish and Snakehead work in the same tank?

[raldywp]

I'm planning on putting my 15cm Snakehead Yellow (Channa) with a 25cm Albino Bichir, 1 oscar the size is about 3 fingers, and a Clown Knifefish size about 15cm in a 70cm×40cm×40cm tank.
I think about the bichir and the oscar they'll do just fine, but idk why im a bit worried about the Clown Knifefish.
Anyone have any experience about this?
Thankyou

Big enough tank almost anything can work, small enough tank almost nothing can work
