GURNEE, IL—According to friends and family members, 34-year-old Josh Ferguson has really been pushing the bounds of credulity lately by ascribing specific personality traits to his seven tropical fish. "This guy here, he's a bit of a loner," Ferguson told reporters Sunday, pointing at a fish who was, at that moment, swimming in a different part of the tank than the other six fish. "And that fish over there, he can be kind of a jerk." At press time, Ferguson was poring over different varieties of fish-food flakes at his local pet store while explaining to a clerk that each of his fish was an "extremely picky eater."
