+1Sorry, but it is dying. What are your parameters, lighting, and flow? Seeing it right next to that gorgonian is telling me you don’t have nearly enough flow for SPS. I imagine light is suspect also.
Gargonian are a high flow coral. They should be bending in the flow.
OP, I don't think anyone mentioned 0 po4 is also a problem. Coral need to eat and this is what they need.
Feed the tank more, some pellets or reef roids will help this.
