Someone I know kept a northern but within the first few days when he opened up the top of his aquarium to feed it, it jumped straight out of the tank, he then returned from were it came
i think i will try the chain, i got some other stuff going on right now, but it doesn't take much to get a idea of keeping a certain fish in one of my tanks, as soon as i see a special or someone else doing it, i want to try, i still can't wait to put in a basement pond once i buy a house.
Here I took a couple new ones for you. He is just as attractive and impressive as a Northern! His name is "Otto." he is currently only 16 inches but chubby and well fed.
