Montipora Nudibranches

[marie]

I don't have them thank god but I was reading Eric Borneman's forum and came across a test he did by puting nudibranches in a sealed jar filled with tank water. The nudibranches lived for 7 weeks with no host and with less than optimal conditions :surprise:. If that isn't a good arguement for quarantining corals I don't know what is

Oh wow! They're hardy little buggers. They're no match for the power of potassium permanganate though :wink:

I had experience with these little bastards a couple of years ago :bad-word:. My in tank fix was blasting the montis regularily with a powerhead, a yellow Coriss Wrasse, Green Wrasse, and a six line Wrasse.

These Wrasses eliminated all traces of the nudis within about 3 weeks. Anyone having issues with these should look for any wrasses in the Halichoeres species.

:biggrin:

oceanic, are you sure you weren't treating for flatworms rather than nudibranchs?

im with you on that, christy

Yeah I am sure, they certainly were not the red planaria type flat worms. I looked at them very closely and they were white greyish nudibranchs, I only had them on one Monti (montipora confusa) They were killing it from the bottomside up.

The Wrasses did the trick, this was a couple years ago and no sign of them for at least that long ago.

My tailspot wrasse ate them too, however it wasn't until I exposed them that he decided they were tasty. I think the scrolling of the M. cap didn't allow him to get his fat head in there. Once I discovered that I indeed had them I wanted to take some photos so I broke a few pieces of cap off and flipped them over (nudis were on the underside) to get a shot of them. As I was focusing the camera the wrasse zoomed over and nipped them off the coral.

the moral of the story: if you're gonna try to get a wrasse to eat them, make sure its a small wrasse :wink:

[chevyjaxon]

will a large neon wrasse eat these things? i dont have a quarantine tank that i keep things in, besides i have no idea what a nudi even looks like:redface:

Here's 2 very interesting articles on these little beggars. I lost a Montipora a few months ago to them and still haven't put another in my tank yet. Nasty little bugs.

Hi

We use for such snails following predators with great success
Halichores cosmetes , i think they are more effective then thesixline wrasse.

We have another tipp against flatworms and monti nudibranches.

We have a small tank with Rhynchocinetes durbanensis
Then we add the coral for 30 min in this tank, after a few seconds the shrimps will eat all nudibranches , eggs and flatworms in a few minutes.
After that you can remove the corals back to the tank

I had Monti Eating Nudi's too....removed EACH AND EVERY monti....added wrasses, cut off any growth that came back for the next while and now have none... frustrating though.....now I have several monti's that are thriving

Honestly, I don't think there is a pest I haven't had...oh wait...zoa eating Nudis...haven't had those....and NEVER will...with dipping, q-tank in use etc....NEVER! (at least one could hope...but maybe I'll just become the resident pest expert!)
