Ok so how many watts of power compacts do you indeed have? Sounds like it could be a light issure but there are also alot of other factors that could play into it. It sounds like you have very little polyp extension which means one of your fish could be harassing it. What are your nitrates like? What's the flow like where you placed the little frag, as sps will often slowly die from the base up when they don't receive enough flow.
