Im lookinng for Zoo's and or Palay's that do well with lower to med light. I have a 54 gal 24" tall tank with a current 2 x 65 watt power compact fixture My L/R is a good 10 " below the top of the tank and i have a glass top on the tank under the Light fixture. I vagely remember some posts of deep water Zoo's or larger polyp's that would do better under lower light conditions. I all ready have Duncans on the list as are Suncoral's Im looking for a Zoo that people have had success with in the shade or low in there tanks where they were suprised by how well they thrived. This is where I feel a deeper water Zoo is the animal Im looking for. Thanks for transfer of knowledge in advance
