What is this?

[glb]

I just saw this in my tank. It’s about 1/2” long. Is it a nudibranch? If so, is it a good critter?

nudibranch of some kind. Maybe zoa eating? Generally not good.

That would explain why my zoas aren’t happy.

Get those suckers, where there is 1 there is more usually. Good luck

Keep a look out for eggs on your zoas.

Yikes! Well the one I saw is out of the tank. What do the eggs look like?

Thanks everyone. I really appreciate the help!

So manual removal is the way to go? Will any dip kill eggs?

Yes manual removal is best imo, dip will kill some eggs but not all. You can also get a Halichoeres wrasse, (or some in other families)most really seem to love to hunt, recently got one(a melanurus then traded it for a marginitus as it hunted even more) to kill off amphipods who were eating my zoas. They are good for many pests. Stay away from the 6 line if you choose that route, mean little guy.
