So I'm hopping on this a little late and for the wrong reason, but if you do find some babies will you let me know? I researched these guys a little bit after watching your video (never seen this before super interesting!) and they seem like they would be beneficial to a reef: spawn readily, good algae eaters, interesting lunar behavior.
In particular I'd like to get a colony going in my refugium (algae is getting bad down there) as I think the 6-line in the display would probably pick them off.
Anyway if anyone has spares of these interesting snails, I'm in the market!
