Can someone help me ID this? I thought it was some kind of egg sack but its slowly moving around the tank.

It's probably going to take more than a bump to get this one ID'ed. You're most likely going to have to take some more pics. If it's moving, you should be able to detach it and take some pics in a dish of water, from other angles. Ideally, I'd like to see close-up pics of it from the top, from the sides, and the front or back if they have any distinguishing features. It might also be helpful if you can get a pic of the bottom, or foot if it has one. Too many things that can't be ruled out from that single photo.

Thanks, and cheers,
