my coral is disappearing

[skoz]

my coral is slowly being eaten or something. It started with my pulsing xenia, then my candy cane coral, and then the hard coral base of my anemone.

Welcome to the site.
Do you have moonlights? Watch at night to find the eater, it most likely is a Bobbit worm. They look like long skinny centipedes. They hide in the rock work. Watch and try and see what rock it is in.

but why is it only three of the corals? i have another anemone thats similar to the other and it's fine.
