Monti-eating nudibranchs?

Hola Luis !!

I lost most of the colonies but the frags that remain show no sign of the little bastards. I dipped an Idaho Grape in lugols but after browning out it just gave up and died about a week ago.
I have to re-think the route on my tank; adding a coris wrasse as a solution might not be wise choice since I have a six line and don't want them to battle each other to death.
The digitatas you gave me were so badly infested they did not survive and most of the caps were also beyond salvation. some small green cap frags are doing OK.
I want to say the infestation is over but won't know until I see the remaining monti frags thriving again.

Happy Holidays Luis !! and everyone on RC
 
I do almost nightly flashlight checks, and noticed these on my purple haze for the first time last night. I haven't added anything in months. Only coincidence was the death earlier this week of my longtime fathead/sunburst anthias. Makes me wonder if he was keeping them in check. I only saw about 8 on the purple haze, then 1 other on an orange cap. The haze is about 12" across totally encrusted on an ~80lb piece of LR. Will have to try in-tank methods.
 
Yes repeatedly, no effect on eggs, not much on adults, I fragged all my montis up and moved them to the frag tank, now just curious how long to wait.

I waited 6-8 months before adding any montis to my tank. I would recommend doing the same
I also added a six-line wrasse to my display and frag tanks.
 
Oh man I guess I'll bump this up because it looks like I picked these pest up from a local reefer. I might just not add any montis for a LONG time. Man this kind of stuff makes me want to break the tank down after almost 2 years! Maybe its time to give up AGAIN. I'll try the fish thing 1st, but from my past experience the only thing that work was Tetra Omed dipping in a separate bucket. I was able to overcome these in my old 150, but it was hard work. At this phase of my tank my montis have out grown a lot of coral and are way to big to be removed for dipping. Lets not forget all the encrusting montis all over my rock work....SIGH!
 
These things suk!
I went through an infestation a few years ago. I tried dips, fish, toothbrush, fragging..all for not.
They are really tough to get rid of.
I watched 5 very large cap colonies get infested from adding one frag.
QT EVERYTHING!
...ended up pulling every monty from the system and put em in the trash.
Left the tank without montis for over a year and that seemed to work.
flash forward...
I just picked up a couple frags from a shop here in Indiana and sure enough, get em home, inspect through the bags and see monti nudibranch infested frags-adults w/ eggs.
I also purchased a mushroom rock from a different display and it had them too.
I have these all in QT right now.
Doubt I will get rid of the pests but Im going to try a toothbrush and lots of time.
I was sooo close to just putting the shroom rock into the display...

*I would also like to know if breaking them causes them to spread/multiply/reproduce.
 
I'm dealing with as well, I found one on the back of my monti I pulled out and diped in coral dip RX, even after 10 min in the dip I had to pry the bugger off with a tweezer, does anyone have any pictures of eggs, I didn't see any but I'm not sure what I'm looking for. I also bought a melanarus wrasse for good measure.
 
I'll take it out again and look, apparently the super glue gel i used thankfully did not make it too hard to get back out lol! Though I suppose if the wrasse is going to eat the buggers I should glue it back?
 
Don't assume the wrasse will deal with the pest, scrub the underside of the coral, my son got a toy microscope thingy and we used it to look at the montis on the TV screen and that's how we found hundreds of eggs so I decided to pull them out of the tank.
 
Just curious, had anyone here just let the monti eatting nudies just eat all there montis? I was just thinking of letting nature take its course and just using the dead montis to mount new acro frags.
 
Well no and yes; I did not let them eat all of the montis, took the caps out and saved the skeletons, let them dry then I used them to mount some corals

Got a sixline and a yellow coris wrass in my 150 gand so far no fighting. Even have another sixline and coris in my 20 G frag tank and so far no fighting. I had the yellows first and then introduced the sixline.
 
Added a Coris Wrasse with caution, little bigger than the Six Line Wrasse, so far so good, no fighting. The Six Line is still a bit of a bully in the tank.
Montis are looking good now that I introduced some back.
The ups and downs of the hobby.
 
Any one tried Interceptor (Milbemycin Oxime), i'd be interested to see what effect this has (if any) on these nudis?
