Here are some general ideas.
Banggai Cardinals - They'll poop on your corals and probably never physically touch your zoas which could cause unneeded stress. Ok, so that may not cause any stress to a zoa. Captive bred are readily available as well.
Mandarin Dragonette - May not be the ideal fish for a new tank, unless it's eating prepared foods. They might be able to keep any pesky pods from bothering your zoas.
Sixline Wrasse - Maybe instead of a mandarin you could go with a sixline. They will help keep any pests at bay. Make sure you tank is covered though, so they don't jump out!
Work's out, I'll think of some more when I get home.![]()
