I work at a pet store where we keep our beardies together as babies and separate the ones that are growing faster. There are currently five beardies about 1.5 inches long. I was cleaning the fish tanks when a lady comes up to me panicked. "something bad is happening". I follow her to reptiles to find one beardie with another beardies leg in its mouth. It's shaking it like a rag doll and there is blood eveywhere. It took me and a manager to pry them apart. The sad thing is "raggedy beardie" lived and was taken to the vet. It's arm looked like it went through a food processor. The Offender, as I call him immidiatly drank a bunch of water and ate 6 crickets like nothing happened.
That little one is def. being walked on by the bigger one. Separate them immediately. Even if you have UV lighting, he isn't getting it if the other is constantly lying on top.
I put them in a smaller tank. the two have been together for quite a while. the big one never lies on top. Just that once where it crawled over to get a cricket. The smaller one is still on worms and pin heads
