Can you help identify this hitchhiker? He showed up about a month ago and has been growing rapidly. He lives in holes in the rock by day; nocturnal / very active at night.
At first I was thinking this could be a baby snail, but the white stripe on the back confuses me. At the time he showed up, I only had Astrea and Margarita snails in the tank.
