Do they open? I agree with Nikki.
they're probably zoas that died...
hmm... maybe they're trying to come back to life? how long have you had the rock in there? it's weird that it would just "appear" on your rock if it's been there for a while...
Okay, so you post some pics and you ask what these things are. You get responces and you say, ''no it can't be''. Where do you think Zoas and Live Rock come from? The LFS? No, live rock come from the ocean as well as Zoas.They hitchhike on live rock all the time.They are bleach out because they don't get enough light or no light at the LFS's holding bins. They will open up if conditions are right in your tank. Btw welcome to MR i hope you like it here. :hug:
