Monti eating nudis - can they hitch hike on other kinds of coral?

[CoralKitty]

so, my battle with the wretched little Monti eating nudibranchs is failing and i plan to start over with a new tank and new rocks because i really love everything in the montipora family, i am rather sad that 80% of my montis are now dead because half my tank was encrusting montis, digitatas and monticaps

i will not be keeping any of the rocks from the first tank because i know the buggars could be in them but...what about my other corals? i have a birds nest, a green toadstool, mushrooms, cloves, a small lobo, some frogspawn, favias and zoanthids which i would really like to keep, but would keeping them risk moving nudis to the new tank? some of them are attached to small rocks...is there something i should dip the corals in first before adding them to a new tank?

just how risky is it to keep the corals? i really do not want to have my new monti collection eaten by the cursed little things, but i really want to keep my other corals, especially my red favia.

Possible, but not likely. They lay their eggs on other Montipora so the larvae have an immediate food source, and I've never seen one not on a Monti. You can Revive dip your corals if you are worried, and then inspect them before adding them to a new tank. People with infestations should just save small frags of their colonies (in another system) and throw the rest away. They are pretty much impossible to eradicate through other methods.

Yes they can. It happened to me, I lost a couple montis but I was lucky to get rid of them with a 6-line wrasse (odds of this method working are very very low, just so you know)
