He’s named it Officer Angry, and it eats like a monster. It looks like a monster too, so that’s not so bad. Videos of the fishy fellow eating are at Cliff’s website: Officer Angry Chases Chow and Officer Angry Eats Off a Stick. The second one is much better than the first. Yes, I shot both, and just as an aside, they were taken with my Clie TH-55 (but edited with iMovie).
Update: the movies are gone since Cliff switched his site around. He says he plans to bring them back.
