I have had my 6 month old bearded dragon for about a week. He seems to have been doing okay. I cleaned out his cage a couple of days ago and took out the exo terra background that was in it. I was gone all day yesterday so I don’t know if he was doing this yesterday. I left food and he didn’t eat any bugs but he ate like his whole salad. but when I got home today he started coming up to the glass and glass surfing and his beard got all black. He would go to the front of the enclosure and scratch at the glass and then go back to his basking spot. At first his beard wasn’t black but it become that way. I don’t know if it was the cat watching him, or me, or what it was. He has never done this before. I have spent almost full days with him and he never did this. I thought maybe it was the reflection so I covered the walls but he still did it again. I have noticed him glass surfing before when I first got him but never this much and his beard never turned black. He his currently in a temporary 40 gallon enclosure till I get a 2x2x4. His basking spot is normally 95-105 maybe 110. He has stopped glass surfing but his beard is kinda staying black. I am just wondering if me coming home could have stressed him out since he is scared of me. Or if there could be something else. The picture is of him a little after his last glass surf. He has stopped for now but his beard is still back for a little while now.
