History and status of applesnail (Pomacea spp.) This species comes in different colours from brown to albino or yellow and even blue, purple, pink, and jade, with or without banding.

Apple snails include species that are the biggest living freshwater snails on Earth. Can reach 155 mm in shell height (Pain, 1960).

The four exotic, nonindigenous Pomacea apple snail species are the island apple snail, channeled apple snail, spike-topped apple snail, and the titan apple snail. When it is night time, the apple snail becomes active and engages in behaviors relating to feeding, as well as mating and laying eggs. Generally, they will also eat any of the microscopic vegetation that grow on the tank rocks or walls. Joshi R.C., Cowie R.H., and Sebastian L.S. Scientific Name: Pomacea canaliculata (Lamarck, 1828) (ITIS) The optimal aquarium water temperature for apple snails is between 18 to 28 °C (64 to 82 °F). In the 1980s, Pomacea canaliculata was introduced in Taiwan to start an escargot industry. These snails sometimes become inactive (especially when first introduced to a new tank, probably from the stress of moving from one habitat to another), and may not move for several days, but once the snail is acclimated it becomes active again. Joshi, S.C. Thiengo, and R.H. Cowie. However, most people will use the common name mystery snail or common apple snail. The island applesnail, Pomacea insularum, appears nearly identical. Their shells have 5 to 6 whorls separated by a deep groove or “channel”. These snails are popular in aquariums, and are also used in the wild as a biological control agent. Ampullariidae, common name the apple snails, is a family of large freshwater snails, aquatic gastropod mollusks with a gill and an operculum. Cowie, R.H. 2002. Biology of a Spike Topped Apple Snail.

In captivity, as well as eating vegetables and fish food pellets, apple snails will also eat other foods if they are available. The list of references for all nonindigenous occurrences of Pomacea maculata are found here. Because of their ability to do this they have become a nuisance in Asia, where they feed on crops.

Taxonomy of Golden Apple Snails (Ampullariidae) Journal/Book Name, Vol. Grana, F. Personal communication. Similarly, the name ‘channeled apple snail’ (or ‘applesnail’), an anglicization of the specific epithet ‘ canaliculata ’, was originally applied to populations in the United States that were thought to be P. canaliculata, but turned out in fact to be P. maculata (Howells et al., 2006; Rawlings et al., 2007).
