somthing munching soft coral polips

[whiteleaf]

hi. got up this morning and found loads of coral polyps with there arms munched off. the coral is mostly pink but the polyps with there arms off are blackened. i presume something poisoned them then ate them as they retract so fast if a hermit wonders over them. thinking it must be a nudibranc and a large one as so many polyps have bean eaten over night.
i have no corals that i have bought just a couple that hitchhiked in on live rock. only have 2 fish and a few clean up crew. was going to wait till finished stocking fish to add coral. do you think whats eaten them would die off when no polyps left? any other suggestions welcome. thank you.

If it's a nudi it'll die off after all the food is gone, you could try putting the coral in a container or right in front of the tank to try and catch it. What kind of fish do you have?

Could just be a bacterial outbreak, or some other stressor as well.

What are your water parameters like? Also, how much water flow do you have in the tank?

It can also be zoa eating spiders. Very ugly little creature...
