My Beardies are fighting

Question
I have 2 female bearded dragons they are about 1 year old. Just recently they have been fighting, i thought at 1st it wasnt harmful but it seems to be getting a lot more violent. One of them keeps biting the others neck and throwing her around. I have already gave them 2 basking spots as the vet recomended but it hasnt seemed to have worked. I dont really want to split them up. Please help!!!

Thanks  

Answer
 I'm sorry Sophie but usually even female beardies are territorial.  Groups only work if the tank or enclosure is truly huge with a number of basking spots and places to eat.  Each beardie requires at least 8 square feet of floorspace.  Groups would be 2-3 females and a male.  You'd need a tank with floorspace the equivalent of a small room with plenty of hides as well as basking spots.
