I bought a young female BCI from JPC Boas back in April. I was told she was 11 months old, and she was roughly 2ft long at the time.
Now she's ~15 months old and she's only grown a few inches. I don't have my records in front of me, but if I remember correctly, she was roughly 340 grams last time I weighed her. She eats one small f/t rat every two weeks (she won't take food any sooner).
As I understand it, BCIs are supposed to reach 4 - 5 ft by the end of their second year. Should I be concerned? Am I doing something wrong? Or do I just have my facts wrong?
