Recently, alot of reefers have been in alot of fuss trying to rid this creatures and prevent them from destroying their priceless zoathid collection. Many have failed while those that are successful in ridding the nudi still have some of their priceless zoos destroyed.

Actually all this fuss can be cut down if reefers put in a little extra effort to dip their zoos in FW before putting the zoos into their tank. A 5-10mins dip into FW(preferbly with lugol solution) should remove most pest that hides among the zoanthids' polyps. Also when choosing zoos, try not to purchase those colonies that are not fully opened. Usually that tells you that the zoos is either stress or being irritated by something. Next, try not to purchase long skirting common zoos(those that are commonly seen in lfs and are sold at ard $3-$5) as zoanthids eating nudis seem to love this kind of zoos compared to the short skirt kind that usually comes from fiji, tonga or solomon island(perhaps the long skirting allow the nudi to hide away from predator).

Zoos that are already affected by nudis:

If you suspect that a certain colony has already been seriously affected by the nudis, its best to throw that colony away and then dip the rest of your other colonies in FW. Dipping in FW only once will not kill all the nudis and definately not the eggs. So its recommended to dip the affected zoos once every few days for few weeks till no more nudis are seen. Within this phrase, one should be dilligent enough to set some time out to pick out all the eggs sac using a tweezers and also wake up in the middle of the night to pick out the adults(they are most active during this time). Lastly, one could engage the service of fishes to tackle the nudi. Wrasses seem to be the best candidate for this job but its not really proven yet.


Meanwhile, happy NUDI fighting :wink:

I fought mine with aggresive FW dipping and spraying (almost every other day)
And the fish helped too as they obviously think that the nudis look like pods

Roughly wats the rest period between fresh water dips?

once a week? or more?

My zoos all closed up/ semi closed up...

[blueheaven]

To be honest, I was quite hard on my zoos as I dipped them everyday (do not try this!!)
I didn't notice any form of death by doing so though

[blacknose]

is there any fish that eats nudis?
canary wrasse? help?

[Doyle]

i used yellow coris wrasse...

[BFG]

The green wrasse that I have seems to do a better job than my yellow coris. The yellow coris may just swim around at times but the green wrasse is doing it's job non-stop, foraging among the rock for stuff to bite. But try to get smaller specimen so that they could go into smaller crevices.

hi, sorry, but is the yellow cori wrasse reef safe?
and what is the green wrasse?
i would love to fresh water dip my zoas but most of them have been spread to the main rockwork.
