Hitchhiker I'd on elephant ear coral rock

[bdieleman64]

I got this elephant ear mushroom a month or so ago. It's normally hand size but was shriveled up and I noticed these. I'm seeing if anyone can ID them?

Maybe majano anemone or possibly aiptasia on the left. Probably want to kill that. Thing on the right is weird, maybe just a tube work/featherduster…?

nah, the one on the left looks more like a clam of some sort. and right is fan worm.
