Hi, I am new to this forum and new to beardies. I just adopted Spike in early August from a friend who rescued him. I am told he is 3-4 years old. I am concerned about his stomach and a definate circle of discoloration. I am wondering if it is a scar from a burn, from a heat rock or pad? His tank had one under the bottom of the glass when I got him but I removed it. Or what could this be? He seems very happy and eats veggies and insects as his diet. Seems like he posed tonight to get a good pic!
