and on the tail,this is not misinformation it is growing back.and one of his siblings lost half a tail and it grew back perfect.
Um... maybe we are not talking about the Australian bearded dragon?
Many species of lizards have the ability to grow a tail. This mechanism is complex, it is associated with the ability to discard the tail in a moment of danger, so that the wriggling tail distracts attention, giving the lizard time to hide.
These lizards have a special structure of the spine, the vertebrae can begin the process of separation, much like leaves do in the fall, and this does not cause inconvenience to the lizard.
After this, the tail can grow back, but it will not have a spine on the grown area and will look different. As I already wrote, this is a complex mechanism and agamas, unfortunately, do not have it.
