this is the Duncan coral I got from doc back last year when he broke his tank down before the move. It has been doing well and made it through the issues I had with my tank. Now the tank parameters are all in range. Only new that I have add is a GFO reactor. I noticed today that the tentacles are short and swelled and a couple of the smaller heads have come loose from the skeleton. I have always kept it on the sand and center of my tank. Any ideas as to why the heads would be coming off?
Kind of what I though. I moved it to a little lower flow area. I'll give it a few days to see if anything changes.
I had one that looked like something burned half of the tentacles on and finally moved it away from everything and it recovered. I think it may have been a bit too close to a blasto and the blasto didn't like it. I just rearranged some corals to put my acans together and now my small Duncan isn't too happy. May be too close to one of the new acans. Going to have to rearrange again. I need another frag rock I think.
