Well I live in Montreal, Canada, and just bought a juvenile snakehead about 3 hours ago... the lfs named it "3 Spot Snakehead". I grabbed the bigger in the tank, he's about 3-4 inches. The smallest fish in my tank is a pair of 6" albino oscars. So hopefully I can enjoy it for a while while it grows, after which he will have a tank of his own.
I dropped the snakehead in with a dozen goldfishes, to keep the others busy. I am afraid my shovelnose will try to have him for lunch. Now he is hiding in the rocks...at least I hope he is and that he did not already disappear
