Midnight hitch hiker's hunt (ID please)

[mrhasan]

Great! Thanks for the info

Can you please give me any tips on how to tell which asterina is reef safe and which is not?

And so that thing is more like feather duster right? I was quite amazed but got a bit worried since it was coming out and going in continuously (even now); just like what porcelain crabs' feeders do. Do you know any specific name for it?

Anyway, thanks again Now I can sleep in peace :P

The 1st photo is of a reef safe asterina.
The second photo is another reef safe not a crab but a worm from the Sabellidae family.
Hope that helps.
