Mysterious Invertibrate Help

[Olly36]

I have recently purchased myself an Aqua One 300 Litre marine tank. About a week ago I bought some new live rock and to my surprise I found a small creature (What looks like to be a sea slug) holding on to one of my corals.

There are some attached files and I was wandering if anyone could identify it for me and tell me if it safe to keep in the tank.

I have heard that sea slugs can be very toxic and can release these toxins into the water destroying everything.

Fixed pictures, you had the whole page copied and not just the picture.

They look like nudibranchs of some kind. I'll move this to a different forum for more help.

Berghia nudibranch, I'd say. They eat pest anemones, but they'll starve once those are gone. Don't worry, this isn't a tank-nuker.

Berghia or Aeolid nudibranch.. Aeolids is very bad.

It's likely an aeolid nudibrach. They eat corals.

Yep. You'll most likely want to remove it.
