Irredescent Shark Catfish

[05niceck]

Hello, 
 
I'm moving house and so will no longer be able to house my current aquarium in the new place. I know my LFS will take in all my fish except for maybe the irredescent shark catfish that is roughly 20cm in length. My current tank is 350 litres so it is already too large for that. I was wondering whether they could thrive in a coldwater pond containing some koi carp and other colder water fish. If not I'm not sure what to do if my LFS doesn't take him in.
 
Thanks,

Sell him on the classifieds, they are tropical and cant survive cold water.
 
or you can cook him. They are pangasius or more commonly called cream dory which are usually used as fillets(I am not joking) if they don't take him
