A common aquarium pet
The apple snails are popular aquarium-pets because of their attractive appearance and size. When taken good care of some apple snail species can reach a large size (15 cm / 6 inch diameter in case of Pomacea maculata, sometimes faulty referred to as Ampullarius gigas). Apple snails are in fact the biggest living freshwater snails on earth.
The most common apple snail in aquarium shops is Pomacea bridgesii (spike-topped apple snail). This species comes in different colours from brown to albino or yellow and even blue, with or without banding. The body of these snails also shows great variation from black to yellow and grey.
Another common apple snail is Pomacea canaliculata, this snail is bigger, rounder and is more likely to eat your plants, which makes it less suitable for most aquaria. These snails also come in different shell and body colours. The Giant ramshorn snail, Marisa cornuarietis, although not always recognized as an apple snail due to its discoidal shape, also ranks the popular aquatic pets.
Occasionally, the Florida apple snail (Pomacea paludosa) is found in the aquarium trade and are often wild collected from ditches and ponds in Florida. The giant Pomacea maculata, raremy makes its way into aquaria. With tropical fish expeditions, sometimes other apple snail species are collected and offered for sale.
Apple snails are often sold under the name Golden mystery snail and are given incorrect names like Ampullarius for the genus instead of Pomacea and species names like gigas instead of maculata. More info about this can be read in the species section of this website.
