They are damn near extinct in the wild anymore. They are highly endangered from habitat destruction and aquarist demand.
You can still get F2 asain aro's. Just not F1, and they will be more expensive then they use to be.
Personally I agree with the ban. I dont agree with fishing an amazing ancient fish to extinction just because of aquarium hobbiests, There are literally thousands of other amazing fish out there. Asain aro's deserve some peace.
