Awesome flower ray, mines still quite pale compared to yours!
What black sand do you use? I can only get hold of Tahitan Moon sand which is pretty sharp or BD trading black sand which only comes in 1kg bags!
Don't use the Tahitan moon stuff, its ****e.
BD trading is the best, you can get it in 20kg sacks but its expensive. I paid £45 about 3 years ago for a sack.
