Should I use my 56 zoa colonies as food?

[Zoaelite]

... I'm really getting fed up with these little pest nems, I have no ambitions to break the reef apart to hand squirt them as I have done this, only for them to return in 3 weeks time. It appears most of them are mojenos so nudies won't fix the problem.

I guess my last choice is some species of fish, I just would prefer something that isn't going massacre my zoas, lps or sps.

After some reading its down to some sort of angel, butterfly or filefish but any insight would be great!
Thanks guys.
