I have a yellow fiji leather that I've moved around a few times in my tank. Trying to figure the perfect spot. How do they like to be placed? Within the rock work? On the edge of the rock? Facing straight up to light or more at an angle? I have two intake blowers pointed at him which he seems to love. He's also about 10-12 inches from a metal halide light. He's currently attached to a smaller piece of rock which I've placed inside another rock...but he's basically hanging on the edge with his center facing about a 45 degree angle toward light.
