From what I have heard, you need a special permit to order them in Canada. Ownership is very restricted and all the fish have special chips in them. Kinda like getting your dog the chip in case it gets lost.
guess we are lucky then.. no restrictions at all regarding asian arowanas here in our country.. the commonly sold is the silver arowana.. 5 inchers are about 600 bucks in our currency...that's about US$10.90...
