I've got a pair of twenty tall tanks and I'd like to replace them with one larger tank thus cutting down on the space the pair of them currently occupy. I'm dealing with a corner space so Aqueon's 54 gallon corner aquarium (39" x 27.4" x 23high) makes sense and that's what I'm leaning towards but it costs twice as much as a 56 gallon column (30x18x24high) and presents a multitude of challenges in terms of equipment like cutting a custom glass top and figuring out how to light the dang thing. The 56 gallon is a full 18" front to back giving me the depth of scape I want but its still a significantly less alluring space to plant. Both would be suitable for the planned pair of angels and school of Harlequin Rasboras. What would you do?
