Congrats! How cool!
My GBR's spawn every 3 or 4 weeks. Sometimes they'll dig a depression in the sand, sometimes they'll spawn on a flat rock.
If you want to hatch fry, keep an eye on your pH. There is a certain pH level over which the sperm aren't able to penetrate the egg and they won't ever be fertilized (I can't remember what exactly...I'm thinking something like 6?). I have a pH of about 7.6-7.8, so I never get fry (which is just as well, as I don't have the time to raise them).
