Should I use my 56 zoa colonies as food?

[Zoaelite]

I tried the light trick last night to no avail, there are far to many to try shelling them all. Any insight as far as fish goes would be greatly appriciated! The tank gets fed really well, and there is a TON of zoas in there so as long as any picking is in moderation I'm fine with it.

It has come down to a tassled file fish, bicolor angel or some species of butterfly.
