They’re simple to keep, no expert or special care needed. What little we know is what’s been found from a quick google on Giant African Land Snails.
Sally lives in a plastic tank thingy that cost around £15 and measures around 18 inches by 8 inches and 12 inches high, though you could just as easy use a big tub. Good layer of compost or coconut substrate stuff kept moist. Her shell’s about 4 inches now (though when we got her last June for No.2’s birthday she was only about 1cm) and they can live up to 10 years. Sally likes cucumber, lettuce and watermelon though isn’t fussed with strawberries. Cuttlefish bone for calcium for the shell
As long as they’re warm, they’re fine. Happy being handled and Sally likes dunking her head under warm water from a tap.
We wouldn’t eat her though
