Polyps sway in the current, open to feed and close when startled, and are generally easier to admire than to keep. The Champagne Pink Sea Polyp offers the admiring part only. Five inches wide and 2.5 inches deep, this ceramic polyp has short, curved tentacles glazed in a muted, slightly warm blush. It hangs on one screw. It does not need water, salt or a light schedule. Of all the pieces in the Coral collection it is the quietest, the one most likely to end up in a bedroom, and the least likely to startle anyone.
