I still have 2 empty tanks!! What to do??

[kuatto]

Made the big mistake of looking in my storage closet and they they were..a 20 high and a 33,just screaming out.I figure I can use the exscuse"honey,lets set up one in the kids room for them"
Any suggestions on stocking maybe the 20 high?Anyone have pics of their 20 gal setup?Tank will be run without a sump,or skimmer,and normal lighting(maybe pc)
