Hi there, well Karrie covered a lot of the questions that could be helpful in determining what's up with your boy. He does look a bit sluggish. Does he have loose substrate and are there fake plants in the tank ? Just to rule out possibility of impaction. It might also be related to an excess of D3 . Dragons that have a strong uvb bulb can be given calcium w/out D3 twice a week but the calcium with D3 only once a week . So eliminate the cal. w/D3 for a while, about 2 weeks, then introduce it only once a week lightly and use regular calcium powder w/out D3 very lightly twice a week. BTW, do you have a meter to read the uvb output ?
