Nudibranch nightmare

[grouper25]

I have set up a 55 which now houses all my high end Zoas. The tank is working out nicely except I have now found nudis in the tank. How they got there is a complete mystery as I dip everything. Based on some of the closed polyps, I know they are eating and bothering my Zoas. I pluck them out when I see them and have even gone through the painstaking task of dipping some of them(ZOAS) if I sense an overly infected colony. I have a 220(FOWLR) and 90(SPS) so my time is becoming more and more limited. I have heard some chatter of late about certain wrasses eating nudis. Has anyone heard this , and if so, what kind???????

Six line, Yellow Coris etc......... Thanks much

some fish will indeed eat the nudi's, but your best bet is to get rid of them naturally. From what i have learned when dealing with those stupid things is that they take on the colors of whatever they are festing on that day; hence the hard time spotting them.
My tank isnt anywhere the size of yours, but I use to just sit and watch my zoas that were closed-up/disappearing for any kind of movement. After a few mins i was able to start spotting them pretty quickly. with some tweezers i was able to eventually get most all of them. It is important to keep looking in the same zoas a few weeks later just to make sure there werent any unhatched eggs (Look for little white dots around the "necks" of the zoas.) Also, fresh water dips helped
HTH somewhat

Thanks, no wonder the buggers have been turning phycodelic yellow------ they are eating my nuclear greens. I am so so done stalking them . The 55 is packed with Zoas and its impossible to dip every colony , many of which are spreading on rocks. The learge ones are easy but its a continum which never ends. A predator may be the only answer............... Thanks

Sixline worked for me...

Red Scooter Blenny I think may be the best.

Between a yellow corris and 3 rounds of flatworm eXit mine are gone.

Nudi are really a pain in the butt once it get into your main tank.

Anyway I solved mine with yellow corris, but not all yellow Corris are build the same, some works and some don't. But do give them some time.
