So far I've had my Dilly for about 5 days, and I'm new to beardie physiology/behavoir. Through the forums I've learned her stress marks are the dark lines from her under belly, and I've realized that since I brought her home they haven't gone away. Now I'm wondering if it's the temp, because the basking spot is 100, and the cool side is 78.....are they to low for her. She's only about 2-3 months old. I have a Reptisun 5.0.....should I buy the 10.0 to increase the temp. I have the lamp as close as I can to the screen, so it's not a matter of adjusting the lamp/bulb. I'm a new mom, and I'm extremely worried about Dilly's health and happiness! Any help will be much appreciated, thank-you!
