I have 2 of them, and they are neither active or shy. They can be pretty skittish if they are surprised, but usually one of mine is found sitting on top of his slate cave, and the other is usually hanging on the roof of another slate cave.
I keep wondering if I have a male / female, one of them is usually a darker gray than the other, with larger spots, but I have no idea how to sex them. I also notice that one of them does an amazing color change at water change time, he goes from being a dark gray to a sand type color, and slowly fades back to gray once he is comfortable again.
