RE: The most sociable reptile pets beside bearded dragon
I actually have to say, I never was a gecko guy, and I basically rescued the three leos I have, and they are very damn cute and friendly. In a little over a week now the two babies I have are already friendly. They both have eaten out of my hand.
Most lizard species are very sociable. But it does entirely depend on the way they are treated and how often someone interacts with them. Even the leos. Almost all of them are like pit bulls. Only most of them are without the ability to kill. If taken care of and loved they all can be the most loving and sociable creatures on the planet. If they are left alone in a tank and just have food thrown at them, not so much. I have taken in beardies that are hell spawn. It's not the dragon's fault, they just aren't cared for and interacted with. Therefore not very social. I could say the same for green iguanas, Savannah monitors, & Chinese water dragons. You ill get more out of them than you put into them.
But as for species that lean toward being very social, leos, red tegus and Argentine black and white tegus, and green iguanas would be the top of my list.
