Live rock hitchhiker?

[Midnighttang]

I'm a total sw newbie. So far I've found aiptasia, some sort of worm that I haven't seen since, and an asterina star. My husband saw this today and asked me if it was anything. I really don't have a clue. ID, anyone?

I also found this on my new zoanthid. It looks like a red mushroom to me. Am I right? Is it okay here or is it likely to hurt the zoanthid?

Yup, blue spotted red mushroom, nice freebie!!
It may cause the zoos around it, to not open, because mushrooms are anemones, but won't hurt it more than that. If you can break the piece of rock off that it's attached to, you could relocate it in a low-med light area.

That's so cool! It's probably safer to leave it where it is for now and just see what happens. I'm likely to damage one or the other if I try and separate them.

Now, I just need to find out what's in the first picture. It could be just part of the rock, but it looks different than the rest...

 

[Flreefer]

Not sure about that one...does it ever open, or does it always look like that?

We just noticed it today and it hasn't moved or changed, even when the lights turned off. It might not even be alive. There appears to be a grouping of three of "them" lower on the rock, where it's hard to photograph. If we can't figure it out, I'll just wait and see if they change at all
