I had my nice rock of star polyps about 2/3 way up under MH lighting and pc's the first day and they opened really nice. Now they don't open and I am assuming a shock from high lighting(my fault). I have moved them down to the bottom of the tank standing up with one end touching the sand! Current is low to medium. Any other suggestions? I know these are suppose to be hardy and occassionally blow stuff off them!
