The layout of your rocks is quite formal. You have nearly the same number on both the left and right sides of the tank, and they are laid out pretty much the same way. This is fine, if you like that. I'm just thinking it might be a little more interesting if you could scatter some of those rocks more randomly, and have some in the middle, maybe toward the back, or add some driftwood. Rocks of different colors, textures and shapes would also add interest. Some could be smooth and rounded like river rocks, others more jagged or ragged. Some rocks could have patterns in them like streaking or striping or mottling, while others can be solid colored. I just think more visual variety would add interest to the overall view, but that's entirely up to you.
I love my Dojos; my Dojos love me,
As long as I feed them, happy they'll be!
