Refugium hitchiker ID? (slug'ish)

[GoFish]

I found this little slug on the back wall of my refugium a couple hours ago, i didn't bother catching it as it looks a little small to do any harm. Its beside a snail in the picture which is about 3/16" around and the slug measures 3/16" wide X 1/4" long approx...
Thoughts, or suggestions?
Its the color of sand or coral

I have a couple of these in my display tank and they are awesome eating algae on LR. Only one time it ****ed me off when one squeezed milky cloudy thingy on one side of the tank and another spawn eggs like million of them.

Thankfully not long after they started, my cleaning shrimp got on it and eat almost all eggs it spawned :D
