Very beautiful tank.
I would never be able to have corals on the sand, my diamond spot goby makes a mess of everything in "the lower 40".
Keep up the good work, and best wishes on the elegance, mine lasted 10 months then died for no reason.
They are beautiful corals but for some reason, don't last long in our pristine water aquariums. Was doing great for the longest time, then one week started to close up. Died within 4 days after that.
