Sorry everyone, I hadn't noticed the new posts.
The tank is very simple to clean, with a python, you just have to get the debris off the bottom in each section. It really doesn't take much more, if any, extra effort on your part.
Unfortunately we had a catastrophe in this tank and all 4 betta's died so it is sitting empty for now. That is the only downfall of a divided tank, but ours was a matter of too much algae killing chemical. I no longer wish to use anything like that in my tanks.
