Greetings,
I just discovered this grazing on the shell of a hermit crab. It is now cruising around on the glass. Apparently, it's nocturnal. I haven't seen it with the lights on. It's about an inch long, doesn't appear to have a shell and it looks like hair or something on its back. Maybe some kind of slug? Anyone know for sure what this is?
