Ive got two lovely boys, one who is super shy and small but also very sweet(baby veiled), and one who is very outgoing and begs for my attention 24/7 (adult panther)
I recommend you leave his cage open for awhile and do something in your room that way he can come out on his own terms, this almost always works especially with the little boys. patience is key and if it doesn't work the first time you can try hand feeding and slowly getting him used to your hands.
