Nudi ID, these monsters were eating my favorite monti...

I am a true believer now in dipping corals. I need to find out what these are and how to get rid of them.

Dont know exact name, but known as zoo eating nudis. Sorry

I thought those were called zoa eating nudi's, guess not since they were eating your monti

I have no advice on getting them out though.. It would take forever to dip everything, but it might be the only way..
Maaan, dial up is soo slow -- beat me to it, janastasio

The most recent item I introduced to the tank was a LPS that was in a tank with alot of zoos. And the lot of zoos are in my other tank.

Do ya'll know if there is any natural, or unnatural, predator of these buggers??

 

[janastasio]

from what I just read on a google search, there is not. Dipping also does not seem to get rid of them either. Taking them out with tweezers as you see them is the best method. Also try and remove their eggs when you find them. Apparently they breed quite readily. There are also monti eating nudi species. Your pics look like the zoo eating species. Good luck. Sorry for your find.

The dreaded monti-eating nudis. Not the same ones that eat zoas, these guys only eat montiporas. You can try freshwater or iodine dips, but that won't get the eggs. Supposedly, dips with Tetra Oomed has been successful, but I've never used it, and I don't know the precise procedure, so maybe someone else will chime in.

Thanks janastasio and yosemite sam. I'm in the right direction now. It looks like the type that only eats montipora and anacropora. I found this, and I really like natural eradication, but I also know butterflies to eat the polyps as well. Maybe sometimes there has to be some kind of trade off.

Natural predators of the nudibranch are butterflyfish of the Chaetodon genus, wrasse of the genus Thalassoma and Coris. Two species of Butterflyfish fish in particular that have been noted as being efficient predators are: Chaetodon semilarvatus, the Red Sea Butterfly and Chaetodon auriga, the Thread Fin Butterfly. Be advised that these fish will also consume worms, such as feather dusters and those that inhabit live sand beds in the reef aquarium.

AAArrrrggghhh dangit!!! I thought I was done with this.

I thought I pulled all my montis out and was safe.
My stupid butt forgot that digitata is still a monti.
