After eating their own shell, the baby snails move straight onto adult food, maturing in six to nine months, depending on temperature and food. These snails grow up to 10mm per month. After 6 months, the Achatina fulica is about 35mm long and may already be sexually mature. Sexual maturity takes 6 to 16 months, depending on weather and the availability of calcium. This snail lives 5 or 6 years, sometimes as many as 9 years.
Snails are one of the easiest of the exotic pets to keep.
Snails should have fresh substrate every week and this should be at least 1-2 inches deep to allow the snail to bury itself as it would in the wild. Mine are rather keen on Peppers, Cucumber and Cos lettuce. They have also eaten apple, nectarine, grapes, banana, peach, plums, etc They will also eat brown bread and moistened dog biscuits. Without this calcium the snails shell will not be very strong and maybe slow to grow. Snails are also fond of the occasional drop of beer.
