Formerly in the genus Asterina, they are now Aquilonastra. There's 33-35 species, most of which are harmless. A couple species that are sometimes encountered in the hobby will harm corals and other invertebrates, although that is *sometimes* they're often benign but can be seen as a pest due to how quickly they reproduce.

Thanks guys! I will not take a chance and kill it. How do I make sure that the chaeto doesn’t come with anything harmful?

how long should I submerge it in tap water? Is tap water enough?

Since were talking about asterina, all that I have are tan. I cant even count how many there are but in the past week I saw a black one. I plucked him and put him in the sump. Any ideas if the black one are safe?

I’m sorry, I could be wrong but I’m pretty sure I read a recent post that a freshwater rinse killed someone’s chaeto. Let me try to find the post.

I can’t find the specific post but @AlgaeBarn doesn’t advise freshwater dips for macro

apparently there are different experiences on this subject. Some say they have always done it and fine and some say not okay.

I inspected the chaeto bag just now and other than asterina I can see a snail as well. It looks like it comes with pests. I can not not to dip it. I know I will lose the copepods that come with it, but I also have apex pods ready in fridge from reef nutrition.

I think the risk of not dipping it is greater than dipping it. Especially, I am setting up a new tank.
