My bearded dragon keeps turning black when he is in his cage and I am very worried about him. I know it means he is stressed but I can't figure out why. I think its between separation anxiety or the cage being to cold. The lights aren't that strong because he is still a baby but I think its time to turn up the temperature I dont know He has a 40 gallon tank he is happy in it but he goes on his cave looking thing an turns black. My mom keeps saying "Oh you take him out to much" or "Maybe because you keep moving him around" I just wanna cry rn I wish animals can talk to you
