So i couldn't resist the urge to just set up a Nano Tanganyika shellie tank here are the specs it is a 3gal Red Sea all glass bow front Caribsea sand, Mini HOB filter with HOB compact lighting.
Very cool! I thought about doing something similar with my 3 blue ocellatus in a 5gal, but just not sure how they'd get along in that small of space. You'll have to keep us posted. That looks great!
