ID of star shaped thingie?

Anybody have any idea what this is. It's the star shaped critter in the middle left of the pic, it is mobile but seems to stay on the same rock and moves very slowly.

 

I don't know but it looks cool 8) ;D I know I'm no help :

 

I've looked all over the net and can't find anything like it!! From the side it looks almost pagoda shaped and it definitely grows very slowly. It came in on a rock with some mushrooms. ;D : ;D

hmmm...maybe a small micro star? lol ill try and find somthing

 

Asterina star?

 

I'ts a sunflower ;D ;D , not sure but it's cool, good lock w/ it hope is reef safe.

 

I now have two of these star thingies!!! I was able to get very close up on one of them and it has a very hard shell. I am assuming it is some sort of snail because of its slow movement. Have not yet seen it against the glass to view its underside but I will post pictures if I can get some. So far completely harmless!!

Here is another close-up

 

I finally got this guy on the glass and it is some sort of snail. I have two of them now and also noticed some baby snails around the tank that appear to be astreas or trochus so somebody actually layed some eggs and a few survived.
