Mine hides most of the time. During the 6 months' I've had one, a medium sized one about 6" extended, I've gone months without seeing him, then suddenly, there he is. Then he'll dissappear for weeks again.
My chocolate chip star in my sump is always out and moving around. But he's not safe for the main tank.
