could it be?

I've been watching this for quit awhile but haven't seen it move. Would find it in a diff. spot the next day ,or not see it for awhile then it would show up. Sorry I don't have a pic. of it, but it's flat and the size of an eraser ,light brown in color with dark brown around the edge . I moved it the other night into a half cf a shell on the bottom and the next morning it had made it's way over to the rocks ,about 3in. away. It kinda looks like a sand-dollar to me ,could it be? Has anyone got any ideas what this my be?

 

Could be a shell-less snail. I've got one. Does your look like a smaller version of this?

 

Marty, thanks for getting back to me . No- this is just as round as it can be and flat, like I said I've watched it for along time to see if it would move, but haven't seen it . It's something thats really slow ,only after hours do I find it moved to another spot.
But thanks for the pic. because I think that is what I have on the back of my tank near the bottom ,just can't really get a good look at it yet.

 

Hmmm, sounds interesting. If you could get a pic that would be sweet, because now I'm curious. lol

 

Looking to pick up a new camera soon, as soon as I find one that would take good shots of my tank I'll try and get a pic. on!!

 

i had something similar, i think it was a snail of some sort, it was flat, dark in color with some white dots, bout the size of an eraser head,and come to find out it was eating my yellow polyps

 

a pic would be very beneficial, lol.

 

sounds almost like a limpet?
