I was going to pose the same question as last week I discovered one on the glass of my tank. It is much much smaller than those in melosu58's tank. It's diameter is at most 1/8 of an inch. It is so small that the legs haven't grown out yet. Looking closely you can see the veins (I guess that is what they are) where the six legs will be. Though I never see it moving I know it does move around as I notice it in different places. I thought I lost it yesterday. When I arrived home from work it couldn't be found. A few hours later it was back on the glass. The Star and a very small clam were the two new finds over the last week. As it grows I'll get a picture. I tried taking one last night but it is too small to see.

They are called asterina starfish. I used to have the same problem. They just took over. They reproduce by dropping of a leg that eventually grows into a full starfish. Mine started eating my coraline algae and were always on my zoanthids, keeping them closed. They were fine in small numbers. Once they got over the 100s I had to do something.

I got 2 Harlequin Shrimp that cleaned them up. I still have a couple left but they are only in my overflows, sump and fug. If you do go with the harlequin shrimp they only eat starfish. So once the asterinas are gone you will need to feed them a choc chip starfish once a month. Just my .02

They hitchhike, usually on coral or live rock. They will eat anything they want. Not all starfish are herbivores. There are also different species of asterinas. Like stated above once they eat everything thats currently being eaten, they will move on to something different. Like my zoanthids.

I leave my back and side glass dirty with diatoms that the these stars eat. Every morning they are on the glass eating it. I have never had them mess with my corals or Zoo`s. I`ve had them for about 5 yrs now. That`s a pretty expensive dinner for your shrimp. CC stars are about 20 dollars around here.
