Esther, it does move. It is jointed(short chain) at the head/body and body/tail, it has an eye hook underneath and is teathered with fishing line to a weight with enough length to move around quite well in the center without tangling on the lilies to much. I really don't think it will be to much of a deterant if a heron returns but ever since DH was a little boy on a trip to Florida he has wanted a gator, so this apeases him.
Mikey, no he has not named him yet, but if the heron comes and gets the goldfish he says his name will be Leaker. The grandson however says maybe Sheldon or Al
