Reefing newb
I included two pictures. One is of the front side view of the slug and the other is the back side. Its small like the size of the back of a bic pen if it was oval. The belly side is peach with a redish circular area at one end. The back side is a brownish color maybe with some black spots. Its never at a really good angle from me to see. From what I can tell it has no shell. I have about 5 of these in my tank that have been pooping up.
