Well, the opinions differ in regards to sand vs gravel. We already know that GF's are diggers and some say they can swallow it and others say that they just spit it out. I've read that fancys normally do less aggressive digging than the standards. If it was me (and it's not!) I'd go with sand for two reasons. I prefer the looks of it compared to anything else and GF's are very messy fish and sand cleans up easily. Detritus merely "sits" on top of sand, where detritus falls down in between gravel.
I don't find any absolute solid info that sand is "bad' for GFs so I think it's simply a matter of personal preference. Since they love to dig, if I had them I'd make sure that they were able to fully enjoy engaging in that behavior. I'd provide either very small gravel to make for easy digging or a larger grained sand so that when they dig in it they wouldn't kick it up into a sandstorm. It's just what I would do, not what you "should" do.
PS. Nice word. I had to look it up...learn something new everyday!
