ID please

Hello,

I’m hoping someone can ID this slug looking thing.
And if I should get rid, if I ever see it again.

Cheers

It’s definitely a nudibranch. With it being on your zoas and it looks like its colors match those zoas I’d guess it’s probably a zoanthid eating nudibranch. If it were me I’d definitely remove it and look for eggs on your zoas.

Agree. Looks like a pest that will cause you issues. Better to remove, dip (for others you can’t see) and inspect carefully for eggs.
