Wow, that's interresting that you got your beardies from the same people! I had emailed Dragon Fortress about housing them together and they told me that as long as they are eating, then there is no problem and that they house beardies together so that they "learn" eachothers behavior from the opposite gender. I'm taking it that is not true. I feel guilty for not knowing beforehand that 2 beardies shouldn't be housed together.
Unfortunatly, I haven't been able to buy a new tank yet. I want to separate them now, but my parents are reluctant to do so because they're not looking forward to buying another tank, another UVA light+ fixture and another UVB Repti-sun 10.0 bulb+fixture. I was going to put one of them in the 20gallon, but we found out that the glass had cracked...
I noticed a switch in the behavior of my beardies, now the male seems to be the dominant one, because he's claimed the highest perch "as his" while the female sits on a rock below. However, they both eat very well and look healthy (they aren't skinny nor have any wrinkled skin). I'm frustrated because I want to separate them soon, but my parents say they don't have the money right now to buy all those supplies. Wish I had money to buy the supplies myself.
