Hmm, well as far as temperament goes here is my experience:
1. Amel got at a year old, so poorly fed he still looked like he just hatched. Did the s shape a lot, rattled the tail a few times, quickly came around now loves being held.
2. Anery (might be dark ghost, really need a hypo male to test grrr) got as a hatchling, from the start would come to my hand to come out of the enclosure. Slither right up my arm. Bit once when I went 4 days late on feeding due to everyone having the flu.
3. Amel Mot het Caramel Stripe. Got as hatchling. From the start jumpy, tail rattling, bitey on feed day, almost every feed day, but only constricted me once. First day after digesting, calm sweetheart, after than back to normal lol.
4. Classic het Amel mot or stripe: Hatched myself. Bit me the day he came out of the egg. After that very mellow sweet guy.
5. Classic Stripe het Butter: Got as hatchling. Never any issues, very laid back and easy going.
6. Amel het anery: Got as an adult (Sr?) this thirteen year old guy is so laid back it scares me sometimes. I think its just that I did not have him the whole 13 years so I did not get to see him slow down. Sometimes he will go a whole minute without a visable breath or movement. Now that is a heartattack waiting to happen to me!
Of course then there are the pair of Classic het lavendars I had that both escaped when we were not home (kind of suspicious given what was going on then but can't prove anything) they were all bite! I had a Jungle that looked identical to a california king except the split scute before the vent. Bite bite bite! Also had a yellow jungle male very mellow for me until he settled in then he would bite any female that came near him. His bites actually hurt, he twisted his head once latched on to get maximum rippage. He had to go with full disclosure. I also had a bloodred hatchling that just up and disappeared during a negative time when other things also disappeared, but could not prove anything. He was so sweet! He was doing something odd too, every shed he had more white on him. I wanted so badly to see what would happen with that.
Anyway, I have yet to see a corn that was down right nasty myself. Scared, possibly abused in the past, but not just plain nasty.
