Scooter - my hitchiker Scutus snail

does it bother your corals?

If it does, it is not noticable. I mostly see it on open rock or the acrylic.

By the way, this pic was taken at night with the flash so thats why corals are closed up.

Nice hitchhiker. I believe they are considered to be algae eaters.

I have one of those as well, didn't know what it was until I saw the pic. Does yours have a thin shell on the back?
