I have a full on 180g SPS tank. Now there are 3 or so Zoa colonies that worked there way in and one paly colony. The paly's do great but the zoa's are soso. They've spread and seem fine at times but often closed and not fully attached it seems. Is there a chemical attack going on from the SPS? Is that even possible? Could the lighting be too intense, I thought they liked that? Any suggestions are appreciated.
