Hitchhiker snail - good or bad

[GTFCTIM]

Got at least 2 of these. Should I be getting them out while I can?

I had one that looks similar to that who hitch hiked in on some Manando rock from Premium Aquatics. Don't know if it's the exact same kind, but I posted a pic on here and no one really seems to know wat it was, but it hasn't caused any harm in my tank yet. Just slowly moves around the tank munchin on algae. If you catch yours up to any mischief post on here plz.

Here's mine, looks similar to yours.

Looks like a nassarius snail. Does it bury itself in the sand?

Doesn't bury itself, just hides in the rocks during the day, and comes out at night.

I've got several nass snails, def ain't a nass. They're like nothin I've seen in the common snails
