i live in the uk, these are perfectly legal to own here, i used to have 2. its got to be complete nonsense that they are fish food though, i had mine from babies, barely 1cm, and within a few months had grown to maybe 3 inches in shell alone, unless you kept maybe 2 adults and continually fed off the young. they lay hundreds of eggs on an almost constant basis, and have both male and female reproductive parts (having a dense moment and cannot remember the name for this) i had mine for maybe 8-9 months and after many clutches of 200+ eggs i decided to rehome them. my friend currently owns 42 of them (where mine came from) and she has to go through the compost twice a day on egg searches, she only started with 2 snails, but missed eggs on various occassions. i dont see why anyone would pay for them though, they are offered for free all over the place, nobody seems to want them, i had mine up for rehoming for 2 months before a teacher got in touch wanting them for her classroom pets. i will never get any again, so far my friends oldest snail is 9inches in shell, well over a foot long when out and about, and is 8 years old, an interesting pet but you cant even go on holiday incase you miss a clutch of eggs as they hatch in just a couple of days, and if your soft like my friend, culling is not an option!
