| || | Just to clarify this one, the existence of Pomacea maculata is not yet proven so I wouldn't technically called them the largest snail there is. They could have been an isolated population of canas or insularums. By far, Pomacea insularum is the largest on record (minus the maculatas until proven this actually exists). Pomacea haustrum would be close second. As far as Vitamin D, it does help with calcium absorption but too much of it can destroy your snails which is one reason I stir clear from Caltrate (with Vitamin D added) and now using Tums. I still use the Caltrate but not as often as Tums which is pure calcium carbonate.

The largest of the snails (one of the "apple snails) is Pomacea maculata. They get to be 6" and live sort of a varying lifespan. They will live much longer at lower temperatures- I'd recommend around 72 degrees. At that temp they'll probably live about 2-4 years, but I really couldn't say.
In order to make a snail grow quickly you want to provide it with clean water, plenty of varied food and calcium. Keep the water hard and alkaline, as that will provide for plenty of nutrients for them to build their shells with. Vitamin D supplements are a good idea as it will greatly improve calcium absorption.
