Zoanthid Garden Disappeared

[MT_is_a_Pisces]

I had 5 - 6 Zoanthids that had grown and started covering a rock. Saturday I noticed they were not all opened and Monday morning gone.
What would do this?
Livestock:
2 Clownfish
2 Chromis
Filefish
Coral Beauty
Tomini Tang

What kind of file fish?

Matted? That one.

Dwarf angels could be also.
