The one I just showed the picture of has been swimming out and about since we got a lot of rock out of the tank. Before that, he used to sit and peek out from under this one rock. His name is Jack. If we went anywhere near the tank, he'd dart back into his rock. I think he likes the freedom now. Actually, I think they all do. I even saw the clowns on the other side of the tank today, and they hardly ever went away from their side of the tank.
The one in my tank has always been out and about. He's been sold and will be leaving on Saturday.
