co-habiting

Question
I have two bearded dragons, both female. Eddie is around 14 months and i have had her since she was a baby. She is living in a 4 by 2 foot tank on her own. 3 months ago i bought Nellie who is a Lawsons/beardie cross and she is 3 years old. she is currently living in a 2 by 1 foot tank on her own. they are both feeding fairly well on greens and morio worms having both decided to go off crickets. i am having alot of trouble with getting Nellie into the larger tank with Eddie as whenever they are near each other Eddie attacks her and bites her, though not hard enough to cause damage yet. Eddie has never shown any sign of aggression before. do you have any tips to get them friendly with each other as i would very much like to have them living in the same tank.thanks!

Answer
Bearded Dragons are actually very territorial animals.  They are not social animals by nature, they are loners and only tend to be together during mating.  Even when two bearded dragons were raised together from birth, you run the risk of them fighting and causing injury to each other.  It would be best if the two dragons stayed housed in separate tanks.
