There are loads of videos out there of people fishing at these pay lakes over in Thailand or Cambodia or wherever. Frankly, I could never figure out why you'd cough up the ridiculous fees some of these places ask to stand on their docks and cast into an aquarium. If I were going over there to catch Mekong catfish or something, I'd insist on a wild one. Of course, that's not to say these club fish don't have muscle. And sorry about the plumber's crack.
