Hi everyone, I'm new to this forum but I've been keeping tarantulas for over a year now. This is my female Brachypelma Albiceps. Shes a juvenile with a leg span of approximately 4 inches. Recently I've noticed that the leg in the picture is discoloured and inproportionate to her other legs. She has not previously lost this leg as she molts at a low frequency so therefore I would have noticed if it was missing. She seems fit and well and she is fairly active for her species and is still eating and drinking. Please could someone tell me what might be the problem with her leg? Thank you.
