I have 2 beardies i just brought to the vet today, they both had calcium deficiency and I dont know what i am doing wrong. they dont eat well (for the last week) have separate tanks the desert sun bar light and a heat light, both tanks are one side 90-95 deg other around 70-80 i had the lights on the screen top of the tank but finagled then inside today thinking maybe the screen is blocking out what they need? ive had my male since Dec. and JUST got the female 3 weeks ago, shes been doing poor the whole time. both seem kinda fat to me neither has lost weight visibly how can i make it better for them? bought both from the petstore and have no background on them. male is 23in female is 17in. They havent been together but my girl seems to be getting fatter, like i said i have no clue what they came from.
