please get your beardie off the calci sand without delay. not only is it way more hazardous than normal play sand (beardies see it as a source of calcium an ingest it deliberately leading to impaction), but your dragon sounds too small to be on particualte substrate anyway.
if you choose to use sand as a substrate, only sifted playsand can be used. you should also wait unitl your beardie is an established size (around 12"
before introducing the sand. if your dragon is the kind who goes aroudn tasting everything, or is a messy eater then sand is not for you.
but please, get rid of the calci-sand ASAP - its dangerous and hideously overpriced. similarly, do not bark, corn or walnut shell.
