zoa eating nudis!
So I got a nice frag for $9.99 at my LFS and I was wondering why this particular frag just kept closing. Of course I thought it was the many amphipods and such that live underneath it that walk across often. Today I looked a little closer and saw a moving head!! this thing looked EXACTLY like my zoa's skirt! I wish I could've gotten a pic but it squished as soon as I used tweezers to take it off :/ I dipped the coral to be sure. Pretty little things but man were my zoas mad!
Anyone have pictures of what eggs look like? I tried to check the coral as well as I could, but didn't see anything nor did I know what to look for. anyway, here's a pic of the coral before, but I don't see any pests. It's still opening as we speak from the dip and me poking at it lol. :lol2: Interesting that these 2 nudis were only one this frag when I have a huge zoa rock and a smaller frag right next door. maybe they preferred this one. https://lh5.googleusercontent.com/_q...0/DSC_0619.JPG |

thanks for the picture! I don't believe I saw any of those. The bases looked clean. makes me wonder where these guys came from. maybe there was 2 eggs I didn't see.

Flat worm exit is a very effective dip against zoa eating nudis. It nukes the adults instantly. You may have gotten lucky with a few adults but I would take a real close look at it in the upcoming days. If you can move it to a more visible area in the tank it would help.

What kind of dip did you do? Rx?

Sea Chems Reef dip is not a good dip for killing the zoanthid eating nudi.
There are several chemical dips that have some success. My favorite atm is Flat Worm Exit in a 3x to 4x the recommended dose. It can be used as a dip or a whole tank treatment in extreme cases. |

It's easier on everything if you can dip all at once outside the tank. FWE is pricey ( to do a whole tank treatment) and it is hard on critters, especially your mini brittle stars.

i used revive. they didn't fall off right away. but with some agitation by swishing in the dip solution and using a turkey baster to blow them off i got them. I dipped 2 times separated by 6 days and i never saw them again. i think i got lucky and got them before any eggs were laid. but i was told to dip 3 times, 6 days apart to guarantee removal (the eggs take 6 days to hatch). I am not sure how correct this is but it worked for me.
i had monti eating nudis at the same time >.< i have those same zoas, they are growing very well. they were attacked by the nudis and by an asterina starfish and they're still kickin'. |

they take on the color of the coral
mine were the purple color of the colonies matting tissue and they stayed in between and on the underside of the polyps. |
I have used melafix to dip my zoas with great success killing zoo eating nudis. They are a pain. I always dip my zoos and quarantine them before putting in main display. Good luck
