Need help IDing this coral!!

[Devildog2673]

I recently purchased this coral at a LFS. The owner said he occasionally gets frags of this coral from a customer who has had it for about 10 years. He doesn't know exactly what it is and said he has never seen anything like it from any suppliers. I think it is some form of acan but the long "Torch coral-like" sweeper tentacles don't look like any I've seen on an acan. I'm including pics of it in "daylight", "moonlight", and of it with sweepers extended.

I think we have to deal here with a Galaxea coral, looking at the encrusting and the sweepers it makes a close match.
What color does it have?

Color is light brown with yellowish-green stripes on polyp edges, with white nodules around the polyp mouths. The mouths are also white. The tips of the feeder tentacles that come out at night glow green under the actinic/uv lights. The tips of the sweepers also are a neon green color
