I am no expert but i have seen a few iwagumi tanks and correct me if i'm wrong but they are meant to look very clean and tidy, which you have certainly achieved with those nice pieces of rock and grasslike plants nestled in between, it looks great, but the heater and HOB filter clutter such a small and beautiful tank. It would probably be expensive to change but perhaps an external filter with inline heater and glass lily pipes? Again i'm no expert, but just a thought, Good luck!
Oh and what livestock are you planning on?
