So my midas was fine literally a couple hours ago. I come back and his anal cavity is just black and he is on the sand bed. Ive had him for a few months and he has been eating everyday and super active. What is this and what can i do? Did he get constipated or something? Its slightly bulged and every few seconds he is wiggling on the bottom. He moved right before i took this photo but he was just on his side out in the open.
