What are these?

[Paul31733]

you usually see nudibranch by sudden dead spots on corals and unexplainable coral recession

Ok I am still learning. So as far as I know they are mostly diet specific... Like zoa eating nudi or Monti eating nudi.
I guess at this point I would be looking for all of them??

just look that all your corals look as intact as they did yesterday, nudibranch eat fairly fast

and you are right each species only eats limited polyps or sponges (or whatever host species they have)
