I have a good-sized snapper that inhabits my pond. When I feed my fish he makes a beeline to where I'm standing. He's fast too. He will even walk out of the water and approach me within a few feet (I'm not stupid enough to hand feed him). But he's pretty tame by wildlife standards. I've gotten kind of fond of him and I guess he can stay as long as he likes. He's a little bigger than a large wheel cover. Occasionally I'll see two other smaller ones, but they have been scarce lately.
