Don't get rid of those melted ones-you may get a surprise
+1, I've had zoas melt on me several times only to come back several months later. I got some BamBams that started out with uber-meltage within a week of acclimation. I kept the frag around and sure enough, they came back with a vengeance! Don't give up. Make sure you're feeding the tank enough. Zoas need more than just light.
Well, she pit them in my nano at work (12g with the original Sunbrite LED fixture). The ones that were fading came back in like 48 hours and look great! A couple that were totally "dead" have developed new polyps.... took up to 60 days, but we see baby polyps on the rock.
Zoas are pretty cool in a nano! They get lost in by 6 foot tank, but in the little guy they are pretty sweet.
Detroit's oldest large LED tank! Est'd Jan 2005, went LED June 2009. 6' wide 130g reef, Sunbrite T10 LED tubes (3xGen 3 and 1xGen 1), mostly SPS, but chalices, other LPS, and a few softies too. http://pjr-reef.blogspot.com/
