Asterina's normally show up on pieces of LR that coral are attached too.

I dip, QT, and started with dry rock and I still have Asterina's in my tank lol

They are a pain. And they do eat algae as their staple, however, in a clean tank … they will move on and start eating other things.

There are lots of articles, and threads all over RC with photos of asterina's munching zoa polyps, and pics and time lapses of asterinas munching on SPS bases as they pass over them.

There is believed to be many many different species of asterina that are almost indistinguishable from one another. The common theme seems to be that 5 legged asterinas are not predatory, but you have to watch closely if you have the 6 legged variety.
