cant help with the id, but in my short time here on TRT, i find its best just to go ahead and put questions like this on the general page. the staff might disagree, but seems to get more responsed.
pretty coral though!! congrats
It is a Lobophyton species of leather. Goes by many names like ridge coral, sometimes devil's hand coral. Usually yellow with ridges extending upwards and small white polyps. Can expand to very large sizes, also deflates periodically, and can shed a waxy layer from surface. Needs good light and current, I think. HTH
