Sorry to tell you this midwest but domestication has indeed changed the dragon. I came in to the possesion of 2 female dragons that shared a large tank since birth. When separated they will not eat. I kept them apart for a week long hunger strike, they wouldnt eat dubia, crickets or even salad. After that week i gave up and put them back in the same tank. The next day they both shared a bowl of salad, to my suprise they really where trying to tell me they liked their home toghther. Now they both thrive and eat every day, they have both laid infertal clutches telling me they are getting closer to being breedable. Futher more they have never been in a fight, no one eats before the other and if they lay on eachother there is no pecking order.
The sceptic will now comment to the stress of the change beeing to blame for them not eating. Well i will remind you that theoriginal cage was not changed in any way except that it was missing 1 sister dragon. If that causes stress enought not to eat then they must like eachother.
Now to address the other issue here. Dont cage a male with a female. If your male finally decided he wants to get it on....your not there to supervise. The male dosnt need protection but the female does. I've seen the horror show a ruff dragon can play on a female. the can bite on to the wrong parts just for the hell of it. In your case they were not born toghther, they probably dont rebell at separation and if yu ever want them to breed i suggest a separation for a moth or more.I would spearate them now and have them breed outside their cages in the summer time. My male is personally at his peek in the summer, some day he will scrach through the side wall of his cage, kick the cats ass and move on to makein his babies after climing to the top of the dresser where he knows his little female is waiting. lol.Well ive ranted enought for 1 day. Don't cage a male with a female, or any dragon toghther unless their are odd circumstances such as my sister dragons.
