Depend on the size of the tank. I would think they could in a large enough tank (like 200g).

 

[erron]

what about a55gal tank.

No, both fish get well over 2 ft long, I believe that both species can get 3ft long, 55s are only about a foot wide.

Here's a profile for a silver arowana: http://aquariacentral.com/species/db.cgi?db=fresh&uid=default&ID=0202&view_records=1 which is most likely the kind you'll be looking at as I think they are the most common.

Both get 3/4+ as long as a 55g.
