Hi. I'm sorry for bothering anyone with questions, but I'm a beginner tarantula owner and I just got a 4" female Aphonopelma seemani yesterday. Just now as I was passing by her home, I noticed a small black patch on her leg. Could this possibly be a sign of her getting ready to molt? Any responses would be appreciated of what signs I should look for when she's getting ready to molt and what I should do to make her molt successful. Also, any tips you'd be willing to give me about taking care of my new tarantula. Thanks.
