What is this?

Hi,
Wondering if someone can help me identify what this is?

I bought a tank second hand and all the live rock came with it. I am currently waiting for it to go through the cycle but I noticed these the other day and there is a lot more then just this one.

Looks like feather dusters to me too.

Def feather, my tank is covered in them!

Thanks. Are they good to keep or should I try and remove them?

Good to keep. They are filter feeders
