anyone know what this is?

It moves around slowly like a snail when it comes out of its hiding spot and there are like 4 or 5 in the area. I'm trying to figure out if I should take them out or leave them in. It's to the lower left of the white polyp, right in the middle of the pic. Sorry about the quality, macro zoom isn't that great on my camera.

If its as flat as I think it is and that purple is coraline. Its a Stomatella snail. They are beneficial algae eaters and are able to reproduce in your tank.

Thats a Stomatella.One of the best algae grazers you can have in the tank.

Thanks! I just saw a white one come out of the sandbed and another white one on the glass that was barely visible, about the size of the head of an eyeglass bolt.

Then this definitely isn't the critter I saw running around the rock a few days ago. It was similar in size but darker and ran in and out of the rock like a cockroach. Couldn't get a shot of it since it was so quick but would anyone know what that is?

Thanks again all. This is an awesome forum.

Yep, stomatella. As for your other critter, it wasn't white or clear, was it?
