Help! What is this?

I bought this cluster of Zoas. I thought they were on a rock but I noticed that the rock had opening and would move when the openings would close. They look like mouths because they would close when I would feed the corals.

#Reefsquad @Lovemyreef2015 any ideas on this hitchiker?

Cool! That looks like a mushroom to me but I honestly don't know for sure. Anxious to see what the other guys/gals think!

Looks like a sea cucumber attached to the rock

Thanks all. I was thinking it was a cucumber. But it doesn’t move locations. It just opens and close a hole. Well there are actually two holes.

Tunicate.

Good ID @Lovemyreef2015 and @KJ you guys are pros

Thanks so much @KJ

Tunicate.

That was my next guess . It always helps when the OP gives enough info to make a correct ID. Cucumbers can and will attach themselves to rocks and not move.

Anyone know the names of those Zoas?
