Weird creatures in saltwater tank.

Question
I found two round, disk-shaped amber colored creatures.  They move or creep like snails & starfish.  They have a hole on their top & sometimes they lay flat & sometimes they form a peak like a shell.
They don't have a hard shell.  They just sort of mold to the surface of what they are laying on.  Yesterday I noticed one had a tan-nish gray color shape on it. I don't know how to get the picture off my cellphone.  But I'll try again.  Thanks.


Answer
if you can get pictures of them onto your computer, you can then attach them and upload them to this message.

Or you can join me at my new forum at

www.thelittleocean.com

uploading pictures is a little easier and you can upload more then one at a time.

you can also get some feedback and responses from other reefers.

so, hope to see you there.

good luck
