The first piece of coral I put in my tank was a green star polup that had a yellow dot in the middle. Did well til one day I noticed not opening then discovered Bristol worm amongst it removed as well as trapped 8 more worms stopped finding in trapp but still not opening or like maybe 4 of like 50 to 60 heads are opening? Any ideas? I moved higher in tank if not open tomarow then maybe lower? I have 105 watt cf
lighting in a 28 g nano cube . I have 6 other corals that seem to be fine. Any ideas?
