Should I be worried

[graeve11]

Got this rock from existing tank at my lfs. Should I be worried? I think I saw something sticking out of one that looked kinda like a feather duster. I’ve had no problem with mucus coming from there yet.

It's hard to judge from the photos - I don't think I see what you are referring to.

Generally speaking, without knowing anything about your tank or your LFS, I don't think you should be overly worried - cultured live rock provides a lot of benefits to your tank which typically outweigh the negatives from having undesired biological hitch-hikers that inevitably come along for the ride.

All those little tubes sticking up. I’ll try to get a better picture

Possibly a Feather Duster from the sound of it:

I wouldn’t be worried. It looks to be a feather duster, which is only a filter feeder

Tube worms or feather dusters?

No way they could be vermetid?

Still can’t really tell from the photos.

Anyway, it’s most likely a Feather Duster, which is safe.

Confirmed feather duster. I waited and got a good look

If you don’t see the feathery fan-like appendages and you do see long webs of mucus, then that would be a vermitid. If you do see the characteristic fan, then its a feather duster.
