#1 there is always room for more info. if anything he can be another example of a failure... but it doesn't seem like hes failing. I don't see whats so wrong about trying something. If it works learn from it, if it doesn't work learn from it.
#2 I have 7, havn't updated the sig, but that doesn't matter, if they were fighting for domination then they surly show it by not moving much, i see them sleeping, curled up together. then i go check on them a few hours from now and one obviously got out and moved around then went back to sleep...if ask me they just curl up together. last one in the hide is the one on top.
but thats my observation with 2 snakes, well and also my breeding male and female also swap spots when their together, one is never always on top, but im sure breeding is a different thing. but where is any evidence that they are trying to dominate each other and not just curling up together because thats what alot of animals do. im not trying to be a jerk eigher, i would like to see some sort of a report saying else wise, i don't see it.
#3 no negative effects observed, I can't say much more than that.
