zoa eatters.. not good for my buddys tank.

[Rydogg420]

So my buddy is always too good to dip his frags before he puts them in to his tank. Even tho I yell at him every time he does this and I say you will regret doing that. he does it anyways. And now he has some zoa eating nudis munching on all his zoas.

What are the steps needed to rid these from his tank? We are removing all the zoas and rock the zoas are on to start with and see if that will help some. but what other methods can we use to kill these beasts and get his tank back to normal? if there are no zoas for them to eat. will they just die off after a month or so when the life cycle runs its corse??

What is the right thing to do now? any help will be great..

Thanks...
