Is this something I should worry about

[robbiederman]

Hi all,
Rob here and I am brand new to saltwater. I have done tropicals and African cichilds etc. So anyways I am cycling my tank with a dead shrimp and live rock. The live rock I got at fish shop cheap, but even just a week in I am seeing life which I am loving. Got some coraline algae on the rocks starting. I saw a few bristle worms feather dusters. The other morning I saw an orange thing growing on the back of one of my rocks. I have tried looking it up, but there is so much out there it is hard to tell with this. I am attaching some pics and asking the experts. Can someone help me out to make sure this isn't something I need to worry about? Thank you so much in advance

Looks like a small duster worm to me... Harmless ,There populations will come and go depending on nutrients in the tank ..
