I just received some Zoa frags today and found this little guy. First I was worried to have found a Sundial snail, but the pattern isn't quite right and the shape makes it look more like a nerite snail. I assume it's just a baby Checkered Nerite (Nerita tessellata), but before I put it into my tank I wanted to make sure.
It's roughly 5mm long (1/5 of an inch).
