My male eastern was probably only about a foot long when he was just a year...but he was probably 2 and a half feet long six months later. I'd say he is full grown now...and I am guessing he is a little over 2 years old....hard to tell because he was wild caught. He topped out at 2 and a half feet. Female easterns can get much larger. Cee Cee is 3 feet long and probably at least 3 years old. I would say that Harley is on schedule...but as a female she should keep growing. She should be at least 3 feet long when she is full grown. I have seen easterns get quite large. Most of the full grown females around here are at least 3 feet long.
