Mine lives by the pump returns in the top of the tank. They are silly little fellows some times. On a related note, I thought my Royal Gramma was a goner the other morning. It was asleep laying on its side in one of my rocks. Didn't move even when I tapped the glass. I went and got the frozen food and figured I fish him out while it was thawing. As soon as the cup hit the water to scoop it up (the water that is...I thaw it in tank water first) he came a runnin' for breakfast! He swims upside down when he is under the rock ledge too. He is an odd one I tell ya!
