Hi guys, my bearded dragon this morning has a black beard and his stomach is twitching. I’m not sure what could be wrong with him. He has an Arcadia bulb. I did switch that out about two weeks ago, do you think it could be a bad bulb? His temperature and UVB are correct I got help on here. I feel like sometimes rarely he does this before he poops and I’m hoping that that’s all that it is.
