The fence lizard is the size of my adult desert iguana. Let me tell you a story.
My desert iguana is a great escape artist. A better Houdini than any of my snakes. I set my adult female bearded dragon on a towel and wrapped her up one day right after a
bath. I turned around to put the tooth brush on the counter and turned back to a sudden squeak. My beardie had her mouth around the base of the tail of my desert ig. He was screeching and there was blood all over, as it was the meatiest part of his tail. I had to spray water on my beardie to get her to let go. I put her away as quickly as possible as my desert ig had immediately ran away. I could not find him, though it was a closed room. He's always come out rather quickly, as he has no fear of people and is not against running to someone and climbing up them.
I woke up one morning after two days of searching and found him on my laundry, having gotten blood all over. The bite was severe and to the bone. The bite became infected a few days later even with treatment and I had to amputate it after consulting my vet. I performed the amputation myself, and my desert iguana now has a stub tail. Had he not been as fast as he was, she would have gotten him around the belly instead and he would have died.
You are severely endangering both animals by allowing this to happen. You do not respect the animals as predators. Bearded dragons in the wild don't just dine on crickets. They eat other lizards as well as rodents along with their bug and greens diet. It is absolutely natural for them to want to eat a smaller lizard. My juvenile bearded dragon spotted my steppe runners from afar and immediately scrambled at his cage to get at them. Instincts are instincts. You may not see predatorial behavior now, but all it takes is a split second. Maybe the grass lizard moves a little too fast and the bearded dragon's predatorial instincts kick in. Maybe you haven't fed the beardie enough one day and it wants an extra snack.
Inappropriate wording removed by moderator. You've made your point, name calling isn't allowed on this site. Added by moderator.to believe that they are bonding and that they are friends. I'm putting this bluntly because after others' posts you don't seem to understand that what you have are reptiles, not mammals. They aren't social. They are instinctual. Respect them and treat your animals properly. Don't endanger them any further. As one poster said already, they look pretty stressed. If you choose to allow them to "bond" any more, please take full responsibility when the accident happens and one of your lizards is dead or severely injured.
