They look like a mini starfish. Every one of them have 5 "arms", some shorter than others, but never more or less. Kind of an off white color. They are attached to the side of the tank. Sometimes I see them on snail shells. I can't see them travel, but they must move because they will be there once & then a few hour later, they're gone.
I do have a large starfish in the tank. Could it be reproducing? My only other (doubtful) thought is maybe it's coral. The tank is not equiped with proper lighting for coral, but we have some live rock that came with some coral (It doesn't seem to be thriving without the lighting).
Any ideas? Thanks!

It's possible they are starfish. I doubt it's related to the one in your tank, though, unless you've got more than one. I would also be doubtful of coral, as most types don't move around. Those that do are fairly recognizable.
I've had baby brittlestars come in on live rock and algae, and a bat star around 1/2 inch on a piece of live rock, though. I would try and identify the type if possible by taking a photograph and posting it on a forum with knowledgeable biologists. Brittlestars are no problem, but some true sea stars may be a problem for other organisms in your tank (eat small fish, crustaceans). I would suggest posting your photo on http://www.wetwebmedia.com/, or at least going through their echinoderm/starfish species article to see if you can recognize yours: http://www.wetwebmedia.com/seastars.htm - also see the "related articles" for other groups related to true sea stars.

These little guys are are pretty much called travlers...... they came from your live rock. They are not bad for the tank. They pretty much hang out. If you get any fish that eat algae...they will more than likely eat these little guys too.
