Zoo Nudis vs FWE, a pictoral

Zoanthid Eating Nudibranchs vs Salifert’s Flatworm Exit

 

BETTER PICTURES COMING SOON!

 

I had initially set out to remove a large mass of flatworms that were on a colony of zoanthids, and placed 8 drops of Salifert’s Flatworm Exit (FWE) into 3 gallons of tank water in a bucket. After 10 minutes, I removed the zoanthids colony, and noted that all of the flatworms were dead at the bottom of the bucket. I also noticed, however, that there were a few zoanthids eating nudibranchs that were also at the bottom of the bucket, whether alive or dead it was hard to tell. Immediately I collected some nudis from a shipment of Solomon Zoanthids that was still acclimating and waiting to be dipped in iodine and freshwater, as usual.

The nudis were placed into two cups, a test group and a control group.

Control group

 

 

Each cup had 2 cups of tank water. Into one cup, there were added 4 drops of FWE, nothing was added into the control group.

In 30 seconds, one of the nudis in the test cup was falling from the side of the cup. In 45 seconds it looked like this.

The results were fast, effective, and much, much less stressful for the zoanthids colonies than the freshwater iodine dip. The control group showed no ill effects during this time. Obviously, the control group wasn’t going anywhere, so 4 drops were added since they were in better locations for pictures.

 

In 30 seconds stress sets in

 

In 45 seconds, lesions appear on the side of the nudi

 

In 60 seconds the lesion spreads

 

One of the nudis appendages falls off at 80 seconds

 

90 seconds it’s falling to pieces

 

 

 

 

 

 

In two minutes, two minutes! Mwahahahahahahhaha!

 

 

 

While not provenly effective against nudi eating spiders (someone please try that one and let me know), this treatment certainly seems to work wonders against zoanthid eating nudibranchs, and best of all it’s pretty reef safe! This means that if you have an infestation in your entire tank, you can now treat with a heavy dose of FWE and get all of the nudis, then retreat every two weeks to deal with the newly hatched eggs. As always, care is required however, since 4 drops per 2-4 cups is nearly 4 times the recommended dosage, and is much easier (and cheaper) to carry out in a bucket than in an entire system. Since this dipping system works with your regular tank water, you can leave the colonies in the bucket for nearly 30 minutes with no ill effects, then place them into a bucket of only tank water for 10-30 minutes in order to remove any FWE that may still be on the colony, and place back into the tank or quarantine system.

Good stuff Miguel!! I just added Tech-D to my arsenal per your recommendation when I was there with Israel a couple weekends ago. Maybe I should add eXit to my arsenal as well?? I ysed to have flatworms on some of my palys, but I haven't seen any in a while, even now 3 weeks after my 6line went MIA on me, it didn't seem to eat them anyways, not that I ever saw at least.

Thank you very much for sharing your findings.

Kudos to you !!

Thanks to everyone for the awesome info. And to the Propagator for his Furan 2 directions in another thread.

I just finished placing all my zoos in freshwater for 30mins (I brought the temp of the FW up to the same as my tank first). I also added FWE to the bath just to be safe. There were a whole bunch of dead nudis left in the bottom of the bucket; hopefully that will do the trick.

 

Is there anyone who is familiar with the life-cycle of nudibranchs? It might help to time applications. For example, if I missed some egg sacks, and assuming that they hatched as soon as I put the zoos back in the tank, how long do I have before they are mature enough to lay their own eggs (ie, perform the second treatment before that time). I would also have to consider the possibility that some nudis layed their eggs right before I nuked them, if that's the case, how long until those eggs hatch (ie, perform the third treatment after that). That way you could kill all the nudis that were born early and all the nudis that were born late, without any of them having the chance to lay eggs of their own.

 

Just a thought. Thanks,

if you dip them every week for 3 weeks they should be fine, their eggs typically take 1-2 weeks to hatch as far as I know

bump because I still see tons of threads asking how to get rid of zoo nudis

[Turkey Baster]

Great information. I may try this on my Zoa's, I've been losing some colonies slowly and have yet to find the source of death.

Nice! Thanks for the info!!
