Hey all, I am considering building a new tank. Based on the layout of my apartment, it's going to have to be taller than long or deep. I am talking 1'x1' footprint, but 2' or 3' high (15 to 20 gallons total). I have 2 questions relating to this, to get an idea of how such a tank would work. First straightforward question: what fish could occupy most of the height of this tank? Bonus point if you mention something else than discus or angel! For my second question, let's assume I "layer" this tank, meaning that I stick hardscape mid level (with suction cups to the back of the tank) and cover said hardscape with soil and/or plants: would bottom dwellers occupy these layers? Or would they still remain all the way at the bottom? Also, any idea / fantasy / DIY shenanigans you might have in mind for such a tank are welcome.
