Yeah as soon as I get the funds and the space I am going to purchase a Mr Aqua 12 gallon and convert it into a divided set-up for my nicer males and females. I love long, low tanks as they maximise swimming space but are not usually as heavy as more traditional style aquariums.
I am going to do something similar to this in my sorority. Except I am going to be using a DIY substrate recipe from another forum and adding in vallisneria and possibly hairgrass as well. I just need to find the right pieces of wood and rock.
I have 3 or 4 T5HO fittings lying around so I figure I might as well make use of them. Plus I want my sorority to require less maintenance and provide more cover for my females.
