Be aware that these are highly restricted for shipping. Aquabid sellers will still ship them to you, but if you are caught both you and the seller can have your snails confiscated and be fined. Just a heads up.
However, the good news is that in some states there are hobbyists or breeders who acquired their snails before the shipping restrictions were in place. You can try to find someone in your state with haustrums.
And ladyblues, yes, they do quite well with spixis! They're huge compared to the little guys, but they are gentle and friendly.
