Despite the damage they can cause, these snails do not bite, but always wear gloves to handle them; they can carry dangerous microorganisms. They are nocturnal so they are active and do their eating at night.


When kept as pets in areas where they are legal, giant African land snails should be kept in secure aquariums. A 10 gallon aquarium is ideal for one of these large snails and a screen top is a necessity for preventing your snail from climbing out as well as for ventilation. The enclosure should be placed in indirect sunlight to prevent the snail from getting too warm. Their ideal temperature range should be high 60 to mid-70 degrees Fahrenheit. It should also be misted regularly to prevent the snail from dehydrating.

Specific Substrate Needs

Giant African land snails shoud have a natural substrate in their enclosure. Compost, soil without chemicals or fertilizers, moss, and dead leaves are good options and will help retain moisture as well. Consider a naturalist enclosure with plant growth for your snail as well!

These snails have big appetites and should always have plenty of fruits and vegetables to feed on. Their food can be dusted with calcium powder to aid in their shell's health or a cuttlebone can be placed in the enclosure. Any food that is not consumed within 12-24 hours should be removed to prevent mold from growing. A very shallow dish or a few dishes of clean water should also be available at all times.
