So I had about 100 of these guys appear in my sump one day. Most of the shells sit empty now, but I have a few fighters who are growing and have found their way into my display. Anyone else think they're turbos?
Edit: Collonista* snail
they are reef safe, algae grazers and good CUC
Will multiply fast if you have extra algae and some detritus, but usually can't go out of control
