Been battling these critters for a month or so. Probably had them in my tank for a while just never had any exotic zoos. I took notice of them after adding some cool zoo frags. Killed many by dipping and siphoned out many at night. I know there are more so the battle will continue. My question is when the eggs hatch how big are the babies? Do they immediatley begin to feast on the zoos, or do they grow to the size that i siphon out before they start their destruction. I am beginning to think the babies which cant be seen with the naked eye are doing damage. Lastly any online retailers have seagrass wrasses available? Thanks Mike

great point, I never seen a baby. I'd dip all my zoo's then put them in a holding tank till i got them gone. i'm sure someone will climb in on the seagrass wrasse, Maybe add like 4 //6 sixline if you dont have any fish they will kill. are harasse I would start me a holding tank and kill them all

One thing i love about the hobby is the challenge of solving the problem, or at least controlling it. My tank is a 180 so the holding tank doesnt seem like the answer. I'm sure there are many of them in the rockwork. The best and simplest answer is a predator. I have eliminated most of the larger ones but wonder if the babies are a problem. When the egg sacs hatch how many babies are there and most of all how big are they? It seems that the zoos are fine one day and the next day they are stressed. Is it the tiny nudis causing the problem. I picked up 2 small yellow coris wrasses which would have helped. I fed a nudi to them while i was acclimating them and low and behold he ate it! Problem was once introduced to the tank my bimac hog went berserk and killed them both. Man this hobby can be frustrating! So the plan is to find a seagrass wrasse or a green coris, maybe the color difference will mellow the hog.

I dunno about wrasses but I got the darn nudi's from somewhere. I have done 3 freshwater dips, one each day and I don't see anymore. I'll keep an eye on them. The nudi's sure do alot of damage fast unchecked.

Hey Sherm, You might as well add lugols to the dip. I followed Muchos method and it did the job without hurting the zoos. I will probably dip them again if i cant come up with a wrasse.

 

[sherm71tank]

Thanks for the tip. If the regular freshwater dips don't seem to be working then I will add Lugols. So far, it seems to be working fine without.

I purchased a Seagrass Wrasse and it reaked havoc in my tank. It turned over everything that wasn't "nailed down" I cannot say for sure whether it ate all the nudis in it's short stay in my tank or my diligence sucking them out and scraping the egg swirls off the polyps.
I have nudis right now in 2 of my tanks and it's killing me. 4 weeks no sign, then "bam" , one giant one and egg swirls. I will continue my routine of scanning with a magnifying glass and a flash light every morning when the lights are out and sucking them out until they are finally gone.

That is not very reassuring. Maybe I like reefkeeping better without zoos? Have you noticed they eat some but not others? I have a colony of RPE's that look great and havent seen the buggers on them at all but other colonies just devastated.

Thanks for the heads up Speck, i'll skip the seagrass wrasse and try a green coris. The trick might be to get a tiny one or five to hunt the little ones. I have looked for a few weeks at the lfs but they only have the yellow coris. Like i said before the yellow coris ate a nudi that i dropped into the bag while accclimating him so you might want to try one. I did try to remove the hog from the display to let the yellows do their work but could'nt catch him.

Thats funny Sherm i have a few colonies of rpes, i got them before they were rpes, 1997 that they dont bother. I do have another colony of zoos that dates back 1997 that at one time grew like the plague. Years back they began to deteriorate. They grew a lot slower and didnt open fully. My guess was the nudis have been keeping them in check.

 

[sherm71tank]

Ehhh,, I don't get. My RPE's and my Eagle Eyes look mostly untouched. Toxic Avengers look to be fairing very well also, mu blue zoos with yellow,green mouthes, getting tore up. Ahh the joy!

Well I have a few egg swirls I plan to raise. I'm looking over the zoas to see which ones are going to donate their lives to science.
I suspect they hatch and go to work.
Photos of the life of the nudi to follow soon.
