We've had our northern blue tongue Raisele for over 8 years now; she's about 10. Way calmer than beardies, but a bit less interactive. They are much calmer and make very soothing pets to pet, with their nice, smooth scales. Easy to catch if you let them wander around. Cheap to feed, too--Raisele's absolute favourite food is garden snails and those, with some banana, mushroom and some fruit and a few other veggies make up her diet. The slower the food, the better she likes it.
