Can anyone help me with this?

IME a crab! I had a bunch of yellow zoa disappear and I eventually found a few big crabs snacking at night... Get a red led torch to prowl the night scape and you will prob found out whats going on...IDKW they like the yellow ones but they cleaned me out of them

Oof, sorry. That was me. I got hungry last night.

Joking aside, not sure what I am looking at here. What is the masses of purple in between zoas? Are those the "eaten" parts?

Be helpful if you let us know what’s in your tank…EDIT - maybe sponge?

The purple is coraline covered rock
