Sean, I personally like that look. You have a lot of caves and tunnels there which is good for the fish, it cuts down on the general agression level. I noticed a lot of people who have agression problems usually don't have enough hiding spots or getaway tunnels in their rockwork. So the fish besically have no place to hide. If you want to create some variety, you can vary the height a little. But IMHO fish don't like pure open space, they like rockwork more.
