Nudie life cycle? help please

[Frunkster]

Hello all

I have been battling with the dreaded nudibrachts for the last few day's & want to find out the best time period to leave between freshwater dips.

I have been using straight tap water rather than RO, which the zoa's cope with but the nudies can't, I dip for 2min's at a time.

But if I can find out the life cycle from egg to hatch I will have a better chance of fighting them with minimal stress on my zoa's.

Any help very appreciated.

I'm sure different people will give you different answers but when I battled them I dipped at least two times a week for about 10 minutes. A 2 minute dip doesn't seem long enough. Also, after a few minutes shake the zoos around to help dislodge any nudis from the zoos. It is highly recommended that you set up a quarantine tank while treating them (10 gallon tanks are pretty cheap compared to the cost of a lost zoo colony.)

Thank you for your quick reply Bobafett, I do have a quarantine tank set up with all my zoanthids in.

I have have been doing the "mix them up thing" when dipping to dislodge resistant ones.

I find dead ones when I dip, are you sure the 2min's is not enough?, as if so I'll extend the dipping time accordingly, just a bit worried about over doing it & killing my prize zoa's.

Any idea what the exact time is on the gestation period?

just get a natural predator like a yellow coris / green sea grass wrasse... 6line or similar types will eat those guys..

they're reefsafe as well... instead of constant dipping which will in no doubt just irritate/weaken or end up killing your zoos in the long run.

No one knows for sure the lifecycle of the eggs, but guesses run from 10 - 21 days approx..... so if you are going to go on a cure path, you need to come at it in multiple directions. Dip in RO with Flatworm Exit or Tropic Marin once or twice a week for a month or so. Add a predator to the tank such as the coris mentioned (though when the yellow and green get larger they could go after shrimp). Manually inspect and remove any egg sacs you find.

Thank you all for your input guys, sorry for the horribly late response by me, but have had issues stripping my system down over the last week & rebuilding.

I have added a Jade wrasse today & fingers crossed all will be well, as he appears to be doing the job, not decided whether it's just my flatworms he's eating or nudies, but give it a few day's & we will see.

I knew some wrasse must eat them, just no idea what to go for as I had a 6 line that did not touch them previously.

I will post how I get on & thanks again folks
