Nice. When we were dating, my now wife had a little tank we setup together. She didn't do anything nor did she care but a lot of people would like it so she was happy. Somehow, I convinced here to have both a 5.5 and a 20 long at the last place she had before we moved in. Honestly, that was more gallons of water than we have now.
My wife is the same way, it has to look nice and maintained. I think she may want a nano for her room, and she would like a little cube in the kitchen after we redo it. Kind of strange as I would prefer to not take on anything new at this point, MTS almost burnt me out of the hobby.
Always nice when your significant other shows interest in a hobby, even if it's just a little bit. I actually would hate if my wife setup her own tank, haha, just like I would hate if she started working on cars.
