I sure hope you guys get to legalize it. May not be able to get it off the critically endangered list as it still remains as it is, but even if the whole US decides to order Asian arowana from my country, I still will not think it will have any impact to the wild population which unfortunately is so rare, breeders are way better buying adults to breed than trying to catch juvenile arowana (that itself is an illegal act too in the country, as the law says only the third generation is allowed for sale, among other conditions).
Catching from the wild is hardly heard of, and most knows better to release them as farm bred ones are usually better in colour and it isn't that difficult or expensive to buy. It's available in almost every LFS all over the country.
