I recently bought a veiled cham from petsmart. Mostly out of sympathy. She was housed with 3 Beardies, another veiled and a uromastix. She has a bite wound from the uro on the last inch of her tail. It is black and brittle then a quarter inch is green then another quarter inch is black again then a healthy tail.It doesn't seem to be infected, rather, it seems like its healed for the most part. I was wondering if there was anything I could do that would benefit her in the long run.
