The most common apple snail in aquarium shops is "Pomacea bridgesii", also called "Pomacea diffusa", (the spike-topped apple snail). This species comes in different colours from brown to albino or yellow and even blue, purple, pink, and jade, with or without banding. Another common apple snail is "Pomacea canaliculata"; this snail is bigger, rounder and is more likely to eat aquatic plants, which makes it less suitable for most aquaria. This species can also have different shell and body colours. The "giant ramshorn snail" ("Marisa cornuarietis") although not always recognized as an apple snail due to its discoidal shape, is also a popular aquatic pet. Occasionally, the Florida apple snail ("Pomacea paludosa") is found in the aquarium trade and these are often collected in the wild from ditches and ponds in Florida. The giant "Pomacea maculata" is rarely used as an aquarium species.
