zoas missing help

[Core]

Every morning I wake up another zoa gone just bought a pack of single polyps on r2r. Only have a pair of standard clowns a flame wrasse and a pretty hefty long spine urchin. Other then the big guy maybe knocking things off any ideas.

Whats the size of your tank, do you have lots of live rock, any corals near the zoas, water parameter?

It's a rsm 250 just seems like either the urchin is bulldozing them or the wrasse I have likes to eat them

It could be a lot of things. I highly doubt it's the flame wrasse and the sea urchin could only do it if it was constantly poking the zoas. It's could be worms in your live rock, nudibranchs, your water parameters, lighting, other corals near the zoas, with the information you've given its hard to tell. I would say its most likely nudibranch or other corals near them. Try waving your hand around them so they close and looking closely for very small brown slugs. If you see them just dip the zoas in a coral/frag dip.
