Does anyone know what this little guy is? Smack in the middle of the picture at the base of the acro. It looks kinda like a star with short nubs and I believe it has a hard shell.

Good, Bad, Keep or Ditch?

Looks like a Spiny Star Astraea Snail to me:

And I can see with their shape they could hitchhike in pretty easy.
