Hello, so I am a new bearded dragon owner and I came across something that I find somewhat concerning. So my bearded dragon's tail keeps going from dark to light and then back again. And it is just half of the tail that does this. It happens really quickly and only takes about 30 minutes from when it goes dark to go back to normal. Does anyone have any advice? I can't go to the vet as the nearest one is far away and I have no way of getting there. Thank you.
