it would look very pretty in your wall tank
Arowanas (only silvers and african and asian) are fine with the following fish as long as the tank is 7foot or bigger:
Pbass,
datnoids,
rays,
most SA/CA cichlids,
giant gouramies,
large catfish,
silver dollars,
large barbs.
The main rule of thumb for an arowana is if it fits in its mouth it is gone, so as long as your fish are atleast half the arows size you will be fine, good luck with it and hope this helps.
PS i have my silver arow with a breeding pair of severums a severum a jaguar cichlid, a perruno catfish and an oscar.
