Gliders personalities are very unique, and over time can change.
Fiona was and always has been sweet. As a Joey she was calm. As an adult, she is easliy skittish, and bounces around. When she's in the hoodie, she calms down, can be held, and petted by strangers, and will go where ever I go.
Dot was so scared and traumatized when we got her. She attacked, bit, crabbed, and hated zippers, and me. I couldn't put my hand near her cage, let alone put in or take out food dishes. She fought us with every gram of strength she had, and never tired from it. It took 3 months to stop attacking, 6 months before I could put her in a tent,and 9 months to bond. She is the beta, I'm the alpha. She tolerates zippers. Barely... She doesn't like strangers, but she will tolerate them. She doesn't bite anymore. If Dot has a choice, she wants to be in her cage, rarely will she settle down in the hoodie. Bonding pouch maybe if we are in a strange place and the zipper is open.
Fiona takes her finger fed snacks along with a side of skin sometimes. Dot is ladylike and careful not to nip.
So, I hope this helps with what to expect from your babies.
Edit: I forgot to add Fiona can take a chunk of skin while having her nails clipped. Not every time, and it's a surprise when she gets me... Dot wants to watch.
