Yes. I would guess it has grown 3/8"=1/2" since I have had it. The key to growth is the feeding. It gets fed at least everyday and sometimes as much as 4-5 times a day. I judge by polyp extension. If they are fully extended, the coral wants to eat. Everything in my tanks, including some fish get target fed with a long coral feeder so I can minimize the waste. I feed them everything you can think of as long as it is fresh, live, or frozen. I do not believe in pellet or flake food. They contain left-over garbage fish meal that has had the nutrients removed and wheat,soy, or alfalfa. Things marine animals have never eaten and are never meant to eat. The pink Spiral in the second photo has to be at least 18" long if strung out. The small yellow Spiral is a frag that broke off of a piece that got broken when a piece of rock fell on it.
