It's my favorite coral, there is also a light green one out there too, ours is just white with a maroon skeleton, we keep ours towards the top of the tank in a low flow area and feed it twice a week with Sweetwater's zooplankton. I started to freak lately because the shape of it looked different and I had thought that the little brittle worm that lived inside was creating a crevice, but that wasn't the case, the polyps were getting longer and that's what gave it a different look. I've got a 40 gallon going now further down the line I'd like to get another Pipe Organ, my husband doesn't know that yet
Good luck and congrats if you get one! Would love to see a pic of the one you get!
