I have a male that's about three years old now, they are pretty slow growers. He's a fast mover when out but completely docile, never hissed or struck. Always been a great eater, climbing the doors waiting for food, eats anything and everything. They get thick but not huge and I'm a big fan of their pattern. Plus with their preference for cooler temps he goes great with my short tails, he's got a rhp hot spot to keep one side of the cage around 83-84 and the cool side sits around 76.
