Yeah, I have to admit I saw a pair of small rays in a tank at SeaWorld in Salem this weekend, and thought "cute! and cool!" But they get to be over a foot in diameter, and like to swim, so I think they're out of bounds. I sort of wish stores wouldn't stock things that are babies, and have no chance of surviving as adults in the care of the average hobbiest. Especially when I see them in stores that I know will recommend inappropriate livestock.
