ID this snail please?

[AlexR]

Picked a few of these up from the beach today down in Florida Atlantic Coast, near St Augustine.

Just making sure these are ok for a reef tank.
My tank is just restarted and getting some age and I need a cleanup crew.

I'm thinking they are nassarius snails.
But wanted to be sure.

I dont know too much about snails, and you should probably post this to the Other Invertebrates section, but i believe ive seen those in threads before. Not nassarius. I dont think they are reef safe, however id hold on until you get a real ID on what they are. But i have seen a lot of snail IDs on Other Inverts., might be a good place to ask
