Your tank length would support the minimum recomendations for a silver arowana upto 28". It'll take a few years for a silver to get that big, at the pointit does get close to 30" you can then determine on if you want to upgrade or not. Most of the advice you get here are from people who have never even seen an arowana, let alone actually kept one. As Chizzle stated, once the arowana gets to monster size you start to have a differing opinion of what these fish need. Though not ideal, your tank could support a large silver aro.
Everyone? One person counts as everyone
Also 30" is not 3'.
The size of the OPs tank is going to have nothing to do with stunting.
I don't see why everyone says you shouldn't.
95% of Silvers don't have the opportunity to be in that big of a tank. I'm sure a Silver would be much better off in your 3' wide than someone else 55 like most end up in.
I think you would be fine.

Also 30" is not 3'.a year and a half to 2 years. It might not even become that big if you end up stunting it.
