About a month ago, the tip of my green anole's tail fell off. He dropped about two cm of the tail after it got caught on something. Since then, the tail has been slowly growing back. While feeding him this morning, I noticed the very tip (like 1mm) of his tail was black and shiny. I haven't been able to find anything online about a black and shiny tail tip, but I have researched gangrene and I don't believe that's the case. I've attached a picture of the tail, and note that he's also a bit stressed.
