First of all, what are ALL of your water parameters, tanks dimensions, and what kind and how much lighting do you currently have??
I must say though, I agree that your brain is wasting away due to lack of lighting. "IMO" If you do not have at LEAST 6 watts per gallon of lighting with the coral placed mid-tank, it will most certainly die. It also needs to be spot fed MEATY foods at LEAST once a week. Preferably 3x a week. Meaty foods include table shrimp, scallops, squid, silversides, mysis, and enriched brine. Chop it up and use a syringe or small turkey baster to "spot" feed it. You should start feeding it ASAP if it still has feeder tenticles that come out either at night or when you feed the rest of the tank, and you really should start slowly moving it up. Like an Inch a week until its at least mid tank, or top tank- depending on your lighting.
Give us some more info and we'll try to help.
Good Luck and Happy Reefing,
