sounds like it might have been impaction
for younger dragons i reccomend a solid subsrtae only but i would use a solid on adults too
paper towels,reptile carpet,slate tile or NON adhesive shelf liner all make great choices
temps should be around 110-115 for basking spot and cool end should be high 70's - low 80's
reptiSUN 10(tube bulb NOT coil/compact) is the reccomended
uvb bulb(alot of others have been causing helth problems) and this should be replaced every 6-8 months
dust with a pure calcium 5x a week
a calcium w/ d3 1x a week and
a multivitamin 1x a week
feed a baby 2-3 x a day as much as he will eat in a 15 minute period
can be anywhere from 40-100 crickets a day
also offer greens as well babies dont eat them as much as adults will but always offer them so they get used to eating them
http://www.beautifuldragons.com has a great food list
mustard greens/collard greens/turnup greens and any kind of squash are the staples add fruit a few times a week
also give them a warm
bath 3-4 x a week
i think i have covered everything but i am sure i will think of something else to add lol let me know if you have any more questions
