Agreed!
I'm not experienced enough with the species, I have 1 male that is over 3 years old, however I have observed a shift in his behavior now that he is fully mature.
Some say the SD and dwarf genetics add to the "flighty" behavior, but that again could is likely an individual to individual trait.
I have a female royal and a female carpet in the same room with my male retic. It is possible, although unlikely he cues in on pheromones from them.
There is a male boa in the room as well.
In a recent thread I described some very aggressive behavior my snake exhibited.
A whole host of others chimed in, and the general consensus was a recent heat wave may have triggered the changes. Folks with royals, carpets and boas mentioned their animals acting differently.
My guy has not completely shifted back to his old ways. As a matter of fact he continues to wait at the door, and I'm certain he'd bite if I just reached in to get him.
Food isn't the answer. I spoke with Garrett Hartle for about an hour one day and he agreed that just throwing food at a snake to settle it down was a poor solution. I feed typically how he would eat in the wild.
That was a bit off topic so I'll answer the question the bast I can.
"I have heard" males tend to run a little hotter than females, and that SD and dwarf species tend to be a little more fired up than mainlands.
That knowledge or opinion comes from a good friend that has probably had 30-40 retics over the years. Its not the first time I've heard that mentioned but it isn't gospel either.
It is a hard question to answer and you will likely get different answers from different people.
What I can say is the retics are an advanced species.
Complacency with even an 8 footer can lead to a bad day.
