Just posted in the reef discussion and posting here again for further info.
I saw a couple of this on the glass this afternoon:

then I saw one on my zoos at evening and now a bit after lights out saw another one on another zoo.
Is this a Zoo eating Nudy branch (spelling?) is it anything else that is harmfull to zoos? is there any need to dip all my zoos or do anyother thing or just leave them be if they are not harmfull?
Thanks for any help

You will need to FW dip and QT every polyp. They will decimate your zoanthids if you do not take action. I would look for Mucho's dip thread. good luck

Here's what a zoa-eating nudi looks like. sometimes they take on the color of the polyps they are eating.

From experience it is a nudi. Zoo eating nudi. Take precautions.

Not all nudis eat zoas.

i got a yellow coris wrasse and it gobbled up all of the ones i had on my tank. great fish if you can find one.

Whatever it is I would get it out, fast.
