Hi guys. I recently bought several frags of zoanthids of various colors and all are looking good except a larger frag of blue zoa's. They are almost all completely closed or just barely trying to open. A few of them look like (sorry but this is the only way I can think to describe it) a little nipple. They are about 12" to 18" under a single 180w 14k MH bulb. Just checked all the water perameters and all looks good including 0-5 nitrates. Everything else in the tank looks good including sps, lps and several softies. I have some of the new zoa's higher and lower than this colony and they are all doing well. Do blue zoa's need more/less light than the others maybe? Any other ideas to what is wrong? Thanks for the help.
