Somethings growing on my rock

[John Hathaway]

Does anyone know what growing on my rock, it’s really small, white and disappears any time a fish goes near it. I see two or three more close it it

Really hard to tell with those pics but based on the shape and the fact that they disappear when fish go near them they could be fan worms. Harmless but pretty filter feeders. Also very hardy.

Thanks, sorry about the pic quality. They’re so small and I’m using an iPhone. That syncs with what someone else has said. Would you keep or remove?

take a gander here and see if you can match them up to the examples.

Keep, they add to biodiversity and have no negative side. Certain fish like butterfly fish will eat them though.
