I have a 3yr. old Tegu. It looks to be a male, by the jowls starting to form. He is only about 24in. total length, maybe more, from what I can remember. He hibernates for 7 months out of the year. In fact he is still asleep now. I would like to get a second Tegu, and am having trouble finding info on introducing another one. Should I go with a similar size or would it be better to add a bigger one. How about changing the cage around and reintroducing both of them at the same time. How about gender? If Tegus are social animals will two males get along? I hadn't thought much about breeding, but if I get a female I can cross that bridge when I get to it.
