I work at a pet store and we have this bearded dragon someone brought in as a baby and the guy said his tank mate bit his tail. So my manager said to keep it in the back and do what we can but (his words) "it's only a matter of time" well that was like 3 or 4 months ago and he has gotten much bigger and his a good appetite. So I guess my question is is this tail rot? Has it spread to his back? How can I treat this??
