Help Me Identify This Critter

[MatsReef]

Found these two fellas hanging out on my pocillopora earlier today. Any ideas?

Thanks!

Some sort of Nudi? I wouldn't want it on my SPS

Definitely appears to be a Nudibranch, I would manually remove it ASAP! The only critter that safely resides in a Pocillopora is an Acro Crab. I have 6 in my tank now and they keep my BOP Birdsnest, Stylo and Pocillopora nice and happy

Thanks! I used some tongs and removed them. Will keep an eye out for any more.
