Nudibranchs No More

I just found this forum, and it is hard to go back and read all 8 pages..can someone tell me bottom line, what is the most effective? We have had our tweezers out for 3 days trying to clear our Zoa's of these nasty little nudi's.

The genus is Halichoeres. As to being reef and shrimp safe, I think this is another one of those cases where it depends on the individual fish. I haven't had any problems with my Yellow Coris Wrasse, and I keep him in a small reef with a fire shrimp.

I've got a Neon Wrasse (Halichoeres garnoti) that I've had for around a month in my reef (mostly in hopes that it will eat nudis). He doesn't bother my two cleaner shrimp or the two blood red fire shrimp I got last week. He is a juvenille though, so I can't vouch for adult behavior.

I don't know if he eats the nudibranchs. I never see big ones anymore, but I've still got a nudi problem. Now when I dip my frags in FW, only tiny nudis fall off, too small to see if left in the tank. I have several times seen the wrasse inspect zoanthid frags, peck at them, and occasionally flip them over and continue to inspect. So he's eating something off them for sure, but I don't think my wrasse alone is the cure. Maybe with FW dips everyday for a few weeks, ugg.

Interestingly, the nudis I have only seem to go after certain zoanthids. I've got a fire and ice colony that's always looked fantastic. I've got two frags of it in different parts of the tank, both look great, never bothered by nudis. I've also got some bright yellows that never show signs of irritation. But other frags are constantly closed up and losing polyps.
 
Well I just did the time compression, read 6 months in one sitting.

To my untrained eye it seems that a wide variety of people have had success with a wide variety of wrasses eating nudis. But it doesn't appear that any one type of wrasse is totally predictable in their desire to eat them. Perhaps then it is more of an individual matter of finding the right wrasse among many. I'm not dealing with this issue right now, but If I was I would probably try out a number of them in order to find one that likes nudi-burgers. (Did I mention that I like Gorgonzolla cheese..Don't all humans?) :D
 
I think my wrasse (Halichoeres garnoti) is eating the larger nudibranchs as I haven't seen one over 1/8" in a few weeks. However, he doesn't get the tiny ones, which doesn't really solve the problem, but I guess he helps contain the outbreak. I'm still FW dipping frags and several tiny nudibranchs fall off, but I never see any eggs. I'm not sure how to solve this problem if I can't find the eggs.

I have ordered some Flatworm Exit as a last ditch effort, since I've heard it may work. It should arrive tomorrow.
 
I have been having good luck with a sixline wrasse. I removed all the zoos from the display and QT'd them in a 40 gal system with the sixline. I have not noticed any in the main and I don't see any activity in the QT system either. I have seen the wrasse hunt and peck the zoos too.
 
I couldnt find any seagrass wrasse, so I have just been giving my zoo's a FW dip. What a pain! I had to empty half the tank. I picked up a green wrasse and he seems to be constantly hunting through the zoo's but i cant tell to be honest if he is looking for copods or nudi's.
All my zoo rock's are now in quarenteen, and i have not seen a nudi in about a week.
How long will any nudi's remaining in the tank survive? anyone know?
 
I have had zoa eatind nudis for abour 3 months. I recently bought a mystery wrasse, he is eating all of the adult nudis.

I still have small nudis and eggs.

most people have good luck with the Halichoeres family of wrasse. all they do is hunt the rocks looking for anything that moves and eat it. seagrass wrasse is in that family

there is a chance he will eat them all before they get to the reproductive stage and eventually eradicate them all .

hands down the most effective solution is to take the rock out and dip it in iodine freshwater (10 drops a gallon) every week until have wiped them out. i personally stopped picking off the eggs and just did weekly dips until they all died.

The idea is you kill all the adults with the dip but then the eggs hatch and then you kill them with the next dip before they reach the reproductive stage. in a month you should be good to go . get yourself a yellow corssis wrasse to be safe : )

I had a prop system completely infested with these . i mean thousands .... after about 6 weekly dips and a few wrasses i haven't see one in about a year now.

imho , dipping will kill them and is the best solution. buying a fish that eats them will help control the populations and have a small possibility of eradicating them.

I had great success with a Neon Wrasse and Flatworm eXit combined. The wrasse alone did not work, though it helped.
 
Thanks to this post I got a Sea Grass Wrass in within three days he cleaned up a total infestation... He is brown though BUT HE worked PERFECTLY! Like a nidi picking MACHINE! If anyone asks I will post pics

Pushed the button twice :( My bad
 
I think that sometimes... LFS sellers may call something a "Sea Grass Wrass" or someone may misidentify a fish and that would also explain some of the variances in Nudi eating habits
