I have a few of these of various sizes in my tank. I thought they were a slug of some sort but I'm not thinking they are snails because they have a shell. I can't seem to figure out exactly what they are but I'm guessing a limpet of some sort but can't seem to find an exact picture of it.
Also do they change color or do I have black and grey ones?
This is the best shot I could get.
