Anyone know what this is?

Noticed this little guy on my live rock. I have a few of them, just wondering what they are and if i should worry?

Thank you in advance for any information you have!

Looks like pineapple sponge. Good filter feeders. Are they mostly in shaded areas?

Yeah. I've never been active in an on-line community before, but it's kind of like family. Except we all have the same interest.

Nope. Just let them do their thing.

Pineapple sponge. No special care required. More will most likely pop up as the tank matures.

They have... we noticed 1 a couple days ago now there are multiple on that rock and a couple others on another rock. All the rock was purchased at different locations we have visited since we started, so we are happy to see them around and now that we dont have to worry its even better!
