It was realistic
If you were looking for something realistic, then you certainly got it. If not for the fact that the numbers came out of the fish like that, I would have thought this was something for the Discovery Channel. The main weakness with this is that there is so little that happens. Next time, you should definitley at least add some music and make it longer. Maybe you could show better shots of the electric eel as he swims around. Real life is fascinating, but you need to make something so realistic more interesting.
