For most people a large tank is very deep, 6' wide, and tall tank... I have been thinking and would like to put a very long tank along a wall in a basement. Tank would span mostly 12 to 15 or maybe even 20 feet. Doesn't need to be more than 30" tall or deep. Would be very long and sleek looking I think. Has anyone done this before and are there any builds on here for it? Have found a few on a Google search but looking for more info on the challenges of this. I.e. Lighting and flow.
