Hello!, i've been concerned with some of my beardies behavior lately. I've had it for just about a month and a half, seems to be only about 3 months old, i've had trouble sexing it ( since its early in age ) but non the less theirs been odd behavior for a couple weeks. It has a 20 gallon exo terra tank, a 150 watt basking bulb which is about a 7-8 inch distance from top to the basking area ( just about 94 degrees F) and the cool side is just about 75-80 degrees F. It's always been content with eating small mealworms that i dust with calcium powder, also has a full and fresh water dish at all times. I recently had moved the tank so that it can watch me at all times around my room because he was getting so un acustomed to human interaction to the point where he was hostile as can be to just my finger no matter how long i took to touch him or how slow i moved. He's gotten a slight bit better with me touching him but heres where the odd part comes in. Anytime i turn my bedroom light off (unless its bed time where hes sleeping as well) he gets dark stress marks and scratches at the glass or will hold himself on a plastic bar and press against the door (for those confused about that statement google the tank exo terra 20 gallon, its longer in length not height) usually after i notice hes pressed up on the glass and scratching,i'll pick him up with ease and hold him. But now it seems he's back to the timid behavior and running away, after i turn my bedroom light on he'll scurry away and carry about his behavior like normal and the stress marks with go away. Anyway i'm not sure what it means and his apitie has somewhat decreased lately as well, he is still using the bathroom normally, just not too much interest. I mist the tank as well, just not sure why he won't really let me touch him without his mouth opening or running away, or why he gets stressed when my bedroom light is off but his lights are still on and perfect temps. Please help!
