New Critter

[jtirone]

I have not added any new rocks in a while, but I just found a new freeloader.
I think I just found a see slug. It appears to have a hard shell, but it is not. It is darker in color, but not black. The shell(?) has coraline on it.
It does look like a snail without the shell.
thanks.

Sounds like a slug to me, most are harmless and eat algae. Keep an eye on it to be sure.
