My 'Apple Snail' is definitely Pomacea bridgesii. It's very aggressive
with respect to plants, plucking away at the plastic plants in the tank,
and chowing down on any green material instantly. (Peas, Algae Wafers,
Spinach, Brocolli, Zucchini, etc) Every time I do a water change in the
tank, Petunia is out there grinding away on the plastic just to make
sure nothing has changed. Petunia's favorite tactic is to park its foot
over the fishes' food, hold the food in its labia and box out the fish.
It'll hold algae tablets by the edge and rasp away with its radula while
spinning it with its foot, like it was a corn cob.

BTW, the AppleSnail site is great, isn't it?

Get the right species of apple snail (Pomacea bridgesii instead of P.
canaliculata) and you can keep it with any plant you wish - it's safe
with plants.

If you've already got canaliculata... well, I don't know of any plant
they won't eat.
