Look up SCUTUS UNGUIS and see if it matches.

Better watch the thread titles. J/K.

To avoid any risk, I'd remove from the tank if I could. Do you have a specimen tank or small QT tank to move it to so you can observe it better?

I've had one in my tank for a long time and hasn't bothered anything hides during the day and comes out mostly at night, presuming its the one that feeds on algae.

too funny, yeah I'd better watch the PCness of my thread title, ouch. Also, please don't give me an excuse to go buy a small tank, my wife will kill me.

Its some kind of Scutus sp. as previously mentioned. These animals extend their mantle to mostly cover the white shell on top, which you can see as a tiny dot in your picture.
