Possibly part of this family, Dendronepthea. Carnation flower comes in many different variety of colors: red, pink, orange, white. The shape of the polyps/flower is depending on the color type of the carnation flower.

AQUACO currently has one in orange color.
If Tee has more than 6 months and thriving, then it's not Dendronepthea and probably a cold coral. The carnation coral is a difficult coral to keep. Although, it's nonphotosynthetic, it's hard to care for because of its feeding requirement. Most just slowly thin out, slowly shrink to disappearance about 4-6 months after purchase.
There was an article on advanceaquarist that posted under RC, two months back, if my memory serves me right.
Very pretty colorful soft coral, abundant and not expensive on market. Just hard to keep.
