My coral has a white slug like pest, it's like a snail but no shell, my coral hasn't opened recently, what is it.?!

Looks like a nudibranch...some are good, some bad.

I found three on the same coral and removed them, will it come back to good health? Its polyps are out but has shrivelled. Thanks in advance

+1 I suspect that’s a nudi too. But i won’t make an ID yet till I know what coral is nearby, do you by any chance have a leather coral nearby?

Yeah I think it's called a purple pussey coral it a was huge before, before and after pics.Also it's the leather they were hosting. Before and after pictures

Ah i see. I suspect what you have is Tritoniopsis Elegans. A nudi that feeds on leather corals.

Hopefully it will recover...many coral are very strong. Even if it looks dead, I'd leave it for quite awhile to see if it comes back. Just check it often for nudibranch babies...good chance there are some eggs somewhere in the tank now.

Thankyou for your help, I removed them and now my leather is coming back to life.

That’s great to hear. Just monitor if they return since they have eggs laid in the rock work. If you start seeing them again, just do the same and remove them.
