Marginella Snails?

The only marginella snail I've ever heard of is Caracolus marginella which is terrestrial, so I doubt thats it.
Hey George. Yup, I'd like to try them. Diversity is always a nice thing. I haven't seen the chiton in a while :worried: but keep in mind I'm usually here at ISU. My mom doesn't do much night tank watching but she knows about what he looks like and hasn't seen him. My other chitons are doing fine and I'm sure theres plenty of algae for him to eat. I got Chitons of the World and tried to ID him but there are many chitons that look just like him except for minor differences. I figured I could rule out the Australian ones but that didn't help much. Thanks for the concern!
