I got my beardie in september. I haven't had many problems with him but lately he is a little lethargic and not eating very well at all. He has had a bowel movement about a day ago so I'm not worried about compaction. He was looking a little dark in color and it has been about six months since I got his UV light so I got a new one yesterday. I have a reptisun 10.0 fluorescent tube. His tale is still pretty dark and I don't know why, and today he won't eat any crickets(which he generally never turns down) or cilantro which is his favorite food. Any ideas?
