Title: Stupid Zoa eating Nudis....
Post by: TechGuy on September 15, 2009, 21:23:57
I moved all my Zoas around. Getting ready to add more rock, setup a 55, and go SPS only in the 120.

I noticed some Nudi eggs, and seen this little dude. Bad pics, but hes the typical Zoa eating Nudi, colored the same as the colony he was under. Nice.

Any suggestions on how to rid my tank of them? So far I have read: 6 line wrasses, Target mandarin. I have both. I also read that Flat Worm Exit will kill them. I have noticed a slow decline in the Neon colony I have, but nothing else.

How about manual removal? FW or iodine dip the affected colonies?

Done and done. Trying to figure out how to get rid of the eggs though.

here is how i do it
works great!!


first dip all the zoos in bucket the water from tank plus add  flat worm exit
after that close check every zoos see if there is egg on it,if u see antyhing look like eggs scrap off with toothbrush
because flat worm exit  will kill the nudi but not egg


after that keep eye on at least month see if anymore show up
if not u are good to go

this is how i treat my zoos
hope this help

You'd be experimenting here, but potassium permanganate is used to kill Montipora-eating nudibranch eggs.  I'm not sure it will work on Zoanthid-eating nudi's, but I imagine it would.

The problem is they take on the color of their food. So that bright neon green in the middle, thats what its been munching on.

I was trying to find my photos of some that were cryptically colored to perfectly match the brown star polyps that they fed on.  I had 3 of them, and they decimated my nice little rock-full of BSP before I caught them.  I just picked the rock up out of the water, the polyps collapse and the nudis didn't - picked them off with tweezers and sent them on their way to Miamisburg Wastewater treatment plant.

Bummer, aren't they?  If you can't pull the rock out and you have eggs - I wish you luck!  Your blue zoas are gorgeous.

If I had some that ate my yucky brown polys that pop up everywhere I would leave them lol.

Are they the tiny blue bumps? or is that entire thing in the middle the nudie?

The blue bumps are on its feelers, the green is the body.

Yeah its not good. Yesterday I dipped all my Colonies. 7 minutes in cold freshwater with flatworm exit and melafix. I shook over 20 Nudis out, toothbrushed all the colonies to get the eggs.

This morning I glance over as I am leaving and spot one on the glass. Little buggers are hard to get rid of. I watched one fertilize an egg coil on my glass a few mornings ago. Kinda neat to watch.
