Looking good Ckuhn003! Phantom looks great!
He just needed to learn to trust you, and vice versa. He also needed to grow up a little and get out of baby defensive, "everything can eat me," mode!
He will probably keep chilling out as he grows and you continue to have positive handling sessions with him.
I got Behira at 430G or so, as a yearling, and was calm as can be. However, she definitely became more comfortable with handling after a month or two of gentle handling sessions. By 700-800G (about 4-6 months after I got her), she was falling asleep half the time she was out, on my chest while I was watching TV or chilling in the reptile area chair.
She still likes to explore and is curious, but half the time, or after exploring, she just curls up on me and falls asleep!
Phantom will get there. Keep up the good work!
