Flatworm eating Nudibranchs -Chelidonura varians

[Chaloupa]

Has anyone ever seen this Nudibranch;Chelidonura varians for sale in B.C.??? It is also called a Blue Velvet Nudibranch. I am in need of some, but the hitch is they ONLY eat flatworms so then will be lending them out....if you have seen some let me know. There was a guy in Ontario that got some in but they sold out very quickly..... here's a pic.
