actually ray, i have some ricordia green w/ orange rim and 1 tricolored one (green body, purple rim and pink mouth) but none of the exotic colored ones in my 46 g bow front. they do nice w/ just the coralife 192 watt light. i have a pale blue one in the nano i have at work 11 g w/ 38 watt light. all of them seem to be doing fine. in fact the one in the nano which has been there for a week is about half way up the tank and really likes in there. the ones in my 46 are at the bottom of my tank. i have found that
soft corals w/ less coloring or the bland looking ones perfer less light. i found this out after owning a white hammer that sunburned to death in my tank =(. so i decided to ask the lighting manufactures about it. i was told that corals w/ less color in them like my hammer were probably shaded or from deeper water so too much light would kill them b/c they dont have that zoo whatever to protect them. and back to the ricordea i plan on buying more of nice colored ones to see what happens. i have read that the ones w/ intense color need to be kept closer to the top of the tank for more light.
