I am trying to provide as many large caves and passthroughs as possible while still maintaining a nice look. This is what I have so far. Please let me know what you think and would suggest. I am planning on adding a "root" type wood feature to the upper left hand side with some greens at the top of it.
Here is the whole tank. Behind the large structure that runs from the middle left is open area. This lets the fish hide if they need to.
Here is the left side.
