A gold-spotted black stin-gray lazily ripples across a stack of algae-covered rocks to 36-year-old Tom Meador's food-laden fist, which looks small, pink and vulnerable poised in the water as the ray glides closer and envelopes it. It hovers there only a moment as Meador strokes the 28-inch ray's underside and then glides away as he laughs.
"She's not really interested in this food," he says, tossing the brown pellet food to the other fish in the small pond. "She'd rather have some frozen fish or shrimp."
Meador shakes the water off his fist and seals up his bag of fish food, glancing around at his other pets. Rather than cats or dogs, gold-flecked piranhas leer out at him, tiny rainbow-colored tetras dart past and an African sultana turtle lurks under a dark deck hidden beneath strands of green vines, a 15-foot palm tree and several orchids.
