Thats awesome! Great looking fish too!
Sign me up for the bet. Though Im gonna wait until the rain stops and give it a go this weekend when good weather is promised. And Ill probably be too chicken to use a single bag, and instead use two.
I might also try something with a "spycam" I have laying around.. somewhere. Its actually a flycam I used to put on RC planes, and you can make timelapses with it and stuff, but the battery is broken. Still might be fun to let it take pictures every minute for a day or two, though I might want something more sturdy than a zip loc bag for that. Perhaps ill use an aquarium turned upside down or something, Ill see.
