zoa eating nudibranchs, need help badly

[Purple Penguins]

so I have noticed over the past few weeks that several colonies of my zoas have been irritated and closed up, been keeping an eye on it but not close enough I guess, today however upon much much closer examination I found several nudibranchs crawling around these colonies, My plan was to fresh water dip each colony, but unsure for how long the dip should take or if maybe there is a better way to rid myself of these pests, all in all I would say I have about 25 diff colonies of zoas I can easly remove to dip, any suggestions? these nudis are about the size of rice or even smaller

thanks in Advance

Any updates on the infestation? If you defeated them, it would be great to share it a motivation for others doing battle.
