Fugetown, I missed your comment about the red bugs. I've seen those things, but they never move. I'll try to get a good macro shot of the area tomorrow. I had looked at them a few days ago, and they actually looked like really small, red polyps of a different color variety.
Maybe I'll just fill the tank with cauliflowers and candy canes - these zoas are definitely not bullet proof :) All things considered, I do believe this could be supplier related. About half the livestock from that shipment was diseased, with several DOA, including 2 damsels. In 20 years of keeping fish only tanks, I've never lost a damsel. They were in horrible shape, and I got about 2/3 of the fish through with chloroquine and prazipro. I cannot understand how some of these well-known, online suppliers stay in business, with the horrific livestock they send out these days. When I started in the late 90s, online livestock was infinitely better than it is today.
