Black snail?

[Bestilson]

I was at the gravel in my tank and I found this! The loach ate the snail but the shell is still there. Have you ever seen a black snail like this??

That looks a bit like a Sulawesi king snail, but if so, that would be unusual. And sad, cause they cost a fortune at this point in time. There are a number of interesting conical shelled snails from that area, the king snail only gets to be an inch long, others can be much, much larger. Some have spiky shells, others don't. Interesting, and really too bad the loach ate it.
