I'm with Bob. We have so much Exotic crap running around down here it's starting to get fun. Yankee, those fish look like Paku, False Pirahna. That's all you can legally buy in the U.S. I have a friend that had 2 real ones for Educational purposes that were amazing. You could drop a Gunea Pig in and it looked like you put it in a Food Processor on High. And That Great Lakes white fish you can keep. I went to one of those Fish Boils in Wisconsin a couple of years ago, well, I'd be glad to show them how to fillet and fry it ,served up with Grits and Hushpuppies.
