I had one for about a year before it died. It was a peaceful neat-looking snail. It usually hid in my sand bed and would be hidden for up to weeks at a time. Every now and then, I would find it on the glass or with its shell exposed.
However, I was told that they prey on some of the beneficial worms in your sand bed and that they are not a good idea for most reef tanks for that reason. I will not be replacing mine.
I have attached a picture of my snail to make sure that we are talking about the same species.
