Dendronephthya are slow to perish, and slower to thrive. To be a responsible reef keeper, you'll need to start researching your corals before you buy them. You had a week to consider your purchase, shouldn't this have been an important step?
And why wait for until you see it decline before you take action? It's much harder to bring a stressed coral back than it is to make it do well from the start. Get the DT's now and start feeding. Don't dose the whole tank, and if you want to feed several times a day, dilute it.
If you want to know what looks bad about it, compare it to these.
