If it's non-photosynthetic (I assume you meant "Gorgonian"), unless you're putting it so close that the heat is a factor, it shouldn't matter. Non-photosynthetic gorgonians are found at higher depths and in shade most times not because they require it, but because they don't require sunlight and have little or no competition in low light areas. Now that said, low light areas are also less prone to algae growth which can quickly take over and kill a gorgonian. You should also keep it in an area of high flow.
You will definitely need regular feedings. I feed mine home grown phytoplankton and it appears to react to Cyclopeze, but I'm not sure if it's actually eating it.
