Any benefits to make it work buying a TALL Tank, rather then a LONG tank? IN my family room...where we pretty much spend much of our idle time, I have a 75 gallon long . I would like another one and can get a sale price right now. Problem is the room is going to be quite full...on solid wall of tv and tank. A tall tank would give me more space....but how do I fill all the levels of a tall tank, and how on earth do I clean and scape the bottom as I am 5 feet tall???? Suggestions??
