What is this snail?

[tgrick]

Okay...bought some branch rock...last of the last I think. Then I noticed this little guy. Before my tank becomes a snail only tank does anyone have a clue what he is? Can't find him. Also, do I keep or remove?! That's the question...

I think it’s just a black nassarius snail

Is it pretty small ? If so, Reminds me of Obsolata

The picture of the cup and fingers provide a size reference. He is not tiny. Thank you guys for all the help. He is in the tank placed inside a fish holder until I figure him out.
