Well.. All coral need light to survive, as they are photosynthetic. Some of them a non-photosynthetic, but i doubt he has any of those because most need a ton of care to survive in a reef tank.
I think... with that light you have you may be able to keep softies. But that's about it. A 96W PC
light over a 125G tank is like having a Normal Fluorescent fixture over a 55G tank. There's hardly any coverage, and the PAR is terrible. But since it IS PC
lighting and not Normal Output, you may be able to keep some softies. But i wouldn't count on those lights sustaining much else.
