AFAIK they all will eat the small asterina's, though I don't have direct experience myself either. I've heard of people using them when asterina's turned bad in SPS tanks. If I remember right, the darker colored asterinas, greyish/black, are more likely to be a problem.

FWIW I came across an article about a seastar that will eat asterina stars.

Simply put and in regards to most if not all animals, once their populations have reached such great numbers and resources exhausted, they move onto other things.

I've got lots of asterinas and literally a xenia forest. The stars dont touch the xenia and I have two types: regular waving hand and pom pom.

They're asterinas, I think. They normally don't bother anythign either, but these xenia's were nearly dead from the SG swing. Maybe that's why they saw it as a lunch.

Harlequins of all ages will eat asterinas as well as other star fish. This is their only food source. Oddly enough they don't eat brittle stars or serpent stars (tankmates), but they do eat choco chip stars (their main diet in my tank) and probably linkias as well. While they will eat asterinas as a snack that is no where near enough, no matter how many you think you have, to fill them up. I have a pair that eat 1 large or two small chocolate chip stars a WEEK!

Please don't get harlequins unless you're willing to feed them other than the asterinas. They'll starve to death before they'd finish off your population and then you'd be back in the same situation with a dead harlequin on your shoulders.
