That eats your zoanthids. I would keep your eye out for more, maybe take the zoanthid colony out and dip it in iodine and blast it with a turkey baster.

If it looks like this

It is a nudi and you may be in for quite the battle. There is lots of info on getting rid of these pests, but it can take a long time. It took me over 4 months of weekly FW dips to get rid of these. You need to look at your colonies at night with a flashlight and you will probably see more. Where there is one there are usually dozens. They take on the colour of the zoas they are feeding on, orange seems to be a favorite.

You need to dip every single colony for about 5 minutes, this will kill the nudis, but unfortunately does nothing about the eggs. They lay the eggs on the stalk of the zoas, they look like a little white spiral. These need to be scraped off outside of the tank and discarded.

Any zoas that have grown onto the aquascaping that you can't dip need to be removed and glued onto rocks that you can dip or be discarded.

If you haven't gotten any zoas for awile and just noticed this you are probably totally infested.

I always FW dip any new zoa I get and look at them carefully with a loupe.

There are very few natural controls, and none that are 100 percent sure. Some wrasses may eat nudis or eggs, but it is very hit or miss. I was lucky to have a six line that ate the eggs and that turned the tide for me.

Sorry to be the bearer of bad news.
