Kilo, your rock and corals look very healthy. The only suggestion I have is to break up the rock work a bit. With a wall of rock against the back glass you will get a build up of detritus which will lead to increased nitrates and phosphates.
I know what you mean that it looks like a wall but I left space behind the rock if you would help me out and tell me how you put my pic up I will post pick of the side veiw. The reason I have what appears to be a wall is because of the center rock which was my first. It is one big rock and has sentimental value. For a while it was the only rock in my tank.
