I bought a frag of some really cool zoas and they seemed fine for 2 or 3 days and now theyve been slowly closing up over the last 4 days and now they're all closed. It doesnt seem to be pox, Ive had that before and I don't see any pests (I did do a lugols dip before putting in the tank), all other corals i bought that day are doing fine.
Any ideas?
