HI today I added some green star polyps and a torch coral to my nano reef tank. I was told to put my green star polyps on the live rock so the things living in the sand don't eat them when my tank lights were on only half of the green star polyps came out and they were all on one side of it does anyone no why only half came out. Also after my tank lights went out I went to see my new torch coral and it seemed to move its polyps so it's mouth was visible is this normal when there Is no lights on? I am a bit worried cause I have never seen my hammer coral show it's mouth in the dark. Please help.
