Zoa Eating Nudi's?

I have a 12g nano and the only corals in it are zoa's. Everything opens up nicely and looks healthy. But at night time when I shine a flashlight in the tank I see little bugs in my zoas.

*If they are nudibranch's how long will it take for my zoas to decline?
*Does anyone have any expierience in this subject first hand if so what did you do about it?

Sorry I have no pics

 

Your F@#$% to put it nicely. Start tweexing them at night. look for small circular eggs, on the zoas them selfs. you can try dipping them in loguls, but I have found to kill them you have to leave them in them long enough to also damage the zoas. I have also found that warm water Ro dips for about 30 seconds will kill almost all nudis. Get a yellow wrasse or a sixline they will help.

 

Ok thanks. Yea I have some lugols solution. But whenever I shine the light on them at night they run of very quickly so how would I get them? All my zoas look great and are open except one whick looks like on the top of it its all white.

 

yeah they will look ok then nudi babies everywhere bad. Already happened to me, see my signature, no more zoas in my display. All in a 15 gal, bad news. Still have nudis too after dipping them all. Once you have them its over, trust me I know. The eggs are somewhere you don't see and the really big ones, also the ones that lay eggs, they come out at night and are the hardest to kill other then tweezing.

 

If they'er running quickly they are more likely copods, nudi's are slow moving (slugs).

 

look up zoanthid sea spiders... also a common hitchiker who stay localized to the zoa's. I had some on a group of zoanthid I bought from a LFS 3 hours away. They're tiny looking little spiders, but easily picked off with a pair of tweezers. Pull the zoanthids out and put them into a small little tank in a bright lit area (sunlight helps to see them), wave your hand in the water to cause enough flow for them zoa's to close up, and then pick them off. Or.. get a photo!

 

zoa spiders and nudis dont run fast
im voting for copapods
google it and see if its them

 

Aghhh it is copopods!! I feel kinda dumb now. Its better than them being nudibranch's though
