So I have had a bearded dragon for about a year and I'm totally in love with him! He's the best. For the past month I have been thinking of something new to get.. I was considering a second beardie but also thought about branching out. I have an empty 55 and 20 gal long laying around and it bothers me that they're empty. So I'm looking for a lizard that relatively easy to care for and friendly. Something that could stay permanently or temporarily in one of the tanks. I think the largest cage I could build would be 4' long by 2-3 ft wide by 4-5 ft tall. So my thoughts were another beardie, a leo or crestie, chinese water dragon, or maybe a Savanah monitor? What do you guys think?
