Their cage looks great! Your Beardie is really big, lol. My Fiance had a Bearded Dragon for 2 years named Patrick and he was a real grumpy guy! He didn't really like people and his beard would always turn black if you tried to handle him.
You could plonk Lenny anywhere and he'd bd happy! I would say he goes from my finger tips to just past my elbow with his tail stretched out. Marge is in their somewhere and she's missing a bit of her tail. Jack took her off somebody his family knew because they broke in and smashed the viv up with her in it and the glass took her tail clean off she's waaaay more timid but you can hold her. Lenny will let you pop him anywhere and feed him etc. he loves being plopped into water haha!
