Is this setup ok for a 200 gallon tank?

[charles-n-charge]

So far I'm planning to have:
1 silver arowana
1 clown knife
2 tiger oscars
2 African brown knives
1 black ghost knife(not sure if I'll do the bgk or not yet)
1 large pleco
And 5 large bala sharks

May add more compatible fish later.

And the silver arowana and ck will be moved to my friends 475 gallon if they end up outgrowing this 200 (7x2x2).

So does this sound ok? And if not then what could be changed or added to fix potential problems?

If the aro and ck are being moved after they get big, then I would say yes, this is a pretty good set up, except that there tends to be aggression between knifefish. I think they piss each other off constantly blasting their little electrical signals.
