I have a 220 gal reef tank I have a creature that just showed up. It is about 1 1/2 inch long, the color is dark purple with a white slit in the back that opens up.
Looks like a mushroom with a snails head.
Nudibranch of some kind?? maybe a limpet are they safe to keep?
I have posted this request on my web site www.aquariareview.com and someone gave me this link to you
Your animal is the 'slug-like' snail Scutus. If you look at the Fact Sheet on the species, and the other messages on the page, you will see it is a fairly common 'hitch-hiker' on 'live rock'. It is also a useful glass cleaner in aquaria.
