Need help Id this snail

[tactical_XJ]

was doing some scaping ( trying to find a coral ) found this snail looking thing, was hard to take off the tank ( barebottom), are these good or bad, it has a hard shell but not like a normal snail.

I like these guys, used to have hundreds of them and they would spawn most nights but my shrimp ate them all pretty quickly when I added them

Be careful when handling them, these critters drop thier tails like lizards when they feel threatened. [emoji28]
