Ramshorn Snail?

Well some one tell me the breeding process and how long do they live for?
Answers:
Ramshorn snails are hermaphroditic, which means that they breed with themselves and don't need another snail to breed, so they are very prolific and the likelihood of having many, many, many more snails is inevitable. Good thing is they stay small at around 1 inch. The life expectancy is short, at best, about 3 years. Part of their life expectancy depends on water temperatures. While warmer waters make them more active and grow faster, it also causes them to die sooner because of this added energy expulsion. Cooler waters will slow them down, in activity, growth and how soon they die.
