Not sure where you're getting your information, but you're nowhere near correct. To say that ALL nudis are predatory is just ignorant. To start with, how many species of Nudibranchs are there? Who knows? You? Me? I doubt anyone knows. I do know that some Nudibranchs are herbivores, which is not a predatory behavior at all.
It is believed that most Nudibranchs are "obligate" feeders. This means that they have a very specialized dietary need. They eat one or two types of foods and if those foods are not available, they starve. For instance, Berghia Nudibranchs are obligate Aiptasia eaters. In the absence of Aiptasia, they starve. Some Nudis eat corals, some eat flatworms, some eat algae....etc.
To the OP, I do believe your particular Nudibranchs are Montipora eating Nudis. I'd inspect ALL of your Montipora very closely and consider treating them for Montipora eating Nudis. It's also important to inspect the underneath of the Montipora for eggs. These can be quite difficult to see and are NOT sensitive to treatment, so need to be manually removed.

Letuce leaf nudi's ONLY eat algae. So they aren't preditory at all.

Also, some predatory Nudibranchs are actually beneficial to us, if used correctly. Berghia is one example.

Letmegrow is correct. ALL known species of nudibranchs are carnivores.
Lettuce slugs are not an exception to the rule because they are not nudibranchs. They are sacoglossans.

rendogg,
I assume you mean that Halichoeres chrysus eats the monti eating nudies. If so, that's good news. My montipora are way to grown into everything to take out and dip.

Wouldn't know how my foot tastes. I'm not the one that made such an "absolute" statement that ALL nudibranchs are predatory. No, you didn't ask how many species there are. However, if you are able to absolutely state as a fact that all nudibranchs are predatory, I'd assume you must know how many species there are.
Maybe it's you who should sprinkle some salt on your toes.

How was my statement anymore absolute than yours ?
We all saw how wrong your statement was compared to mine, but that's not the issue you want to chase.
Ask a question to receive information, don't ask a question to pose a challenge (which you conceded to with your ignorance of the subject).
I would rather speak the absolute truth than to speak a false equivocation.

So you're asking me how feet taste wasn't "posing a challenge" huh?
I stand by my statement. I do not believe all Nudis are predatory, nor do I believe they're all carnivores. In fact, there are a lot of Nudis that eat corals. This isn't a carnivorous behavior. That would make them either Coralavores, OR herbivores that are eating zooanthellae, which is an algae.
I also stand by the statement that making a blanket statement that "ALL nudibranches are predatory" is ignorant. Ignorance is defined as lack of information. I don't believe enough information is known about the many species of Nudibranches in the ocean to make such a blanket statement.

Hypselodoris bullockii, which IS a Nudibranch, NOT a slug, eats Sea Sponges. Is this predatory or carnivorous?

CORALS ARE ANIMALS
Your credibility just hit rock bottom.
What website are you getting your info from ?
It sure isn't RC because I am sure everyone here knows that Corals are animals. NEWS FLASH ! Sponge are animals too !!!
Name ONE thing a Nudibranch eats that is NOT a living multicellular organism in the Animal Kingdom. THAT is my challenge to you.
I know what the definition of ignorance is, you are displaying massive amounts of it right now.
