Very well saidI have watched Asterina mow down my healthy zoanthids. I have an acquaintance that discovered a pink variety eating his prized sps at night.
Since that are hundreds of different types with different feeding strategies, and some becoming opportunistic eaters it's extremely difficult to make generalizations. If you see them grazing on the glass on film algae, and you see them reproducing asexually by leaving legs behind to regenerate than yes you likely have a variety that is an algae eater, but has the potential to become extremely invasive.
If I see a variety hanging around a certain coral type then I intervene.
Asterina are much like Flatworms in that there are so many types you really have to deal with them on a case by case bases, and what works for you.
I recommend that you start a new thread in the newbie section and also read as much as you can thereI just bought a ocean revive t227 led for my 30 gallon long tank and it's 18 inches deep and I got a couple of soft corals and a couple of anemones and 1 is a rose anemone and I was wondering what I should set the intensity at for the corals and anemones and I had a led light before this light but it was only a strip light that was 14 watts cause I just bought the corals so I had to get a better light so I got this light but I really don't know what to set the intensity up to so hopefully someone can help me with this so I don't kill anything
this forum is great when it comes to help wish I could help more but I am still a newbie myself
