Careful, I cant tell his age from the pic, but you really want to be careful with the calci-sand if your B-Dragon is young. At least 6-9 inches in length is my advice to avoid compaction. After 6-9 inches then it would be safer to use that calci-sand. I liked B-Dragons, but I prefer a Uromastyx or Horned Lizard. I wish chameleons were as easy to care for as desert herps.
