Carolina Custom Cages Phoenix Worms Dishes, 3 each We like these Phoenix Worms Dishes because they are functionally perfect in several ways. Since were feeding a specific number of Phoenix worms per day to our baby dragons, we can be certain that the Phoenix worms dont get lost in the habitat and our baby dragons can find them readily. The dish is just tall enough so that the Phoenix worms dont get out, but still are a shallow enough depth for the baby dragons to reach in for them easily. Most important, the dishes are made from polystyrene plastic, so the baby dragons can see through the dish for the treats inside! The Phoenix Worms Dishes measure 3-1/2 in diameter by 9/16 in height; made from polystyrene plastic. We do recommend washing by hand to avoid chipping.
