Nudibranch?? Need id!!

Just saw it creeping over some zoas. Removed it since I didn't put it in my tank intentionally.. Any help would be awesome.

 

It's almost orange/yellow under actinics if that helps....looks pretty cool so I'm assuming it needs to die

 

It's a zoanthid eating nudibranch so unless you want to feed it than yes (sorry).
You're going to have to check the frag for egg masses, white and spiral (google images if needed) remove eggs with Q-tip. Next you'll have to keep checking until you find no egg or adults. They are pretty though.

 

Thank you!!

 

You're welcome.
