I’ve been reading the forum posts on this, is there anyway to know what type of asterina this is, or rather anyway to know if this is a coral eater?

Same here. That’s all I’ve heard but nothing definitive. If you’re concerned I’d suggest puling it out. They multiply quickly in our tanks so I think this is one of those situations where you should err on the side of caution.I don't know if it's true, but what was told to me years ago was that the white/light colored ones are reef safe, and the dark colored ones are potential coral eaters.
You can watch it, if you see around it zoanthids than it's probably dinning on them at night. Totally agree that precise ID is almost impossible. My experience is that blue to grey in coloration were coralline eaters, pink coral eaters, but that is my personal observation. I have never had the issue with population explosion though.
I have an outbreak of asterina and plan to get a harlequin to eat them all up. Done this before, then gave the harlequin back to the lfs when done.
Problem now is that since the last outbreak, i had purchased a sand sifting starfish. My first one, it is quite effective in keeping my sand bed clean, and has been an awesome addition to my cuc.
I know the harlequin will eat him up along with the asterina, so looking for options. Anyone go down this path?
Was thinking to keep the sand sifting starfish in the sump for a while, but didn’t want him to starve.
Thoughts?
