How long an apple snail lives?

Answers:
The apple snail's life expectancy mainly depends on the temperature of their environment and the general life conditions. At lower temperatures, the apple snail can get over 3 years old and records of apple snails of ten years old have been reported. Lanistes nyassanus has an estimated life span of 5 to 10 years in Lake Malawi, Africa.
At a temperature of 25掳C, they will only live 12-16 months. At higher temperatures, the snails are more active because their metabolism increases with the temperature, but this also speeds up their life cycle and thus shortens their life expectancy.
So you can elongate your snail's life by lowering the temperature. A general rule: keep the temperature between 18 and 28掳C (65-82掳F).
