My old Nano Cube 12 (original model) has been a fixture in the room my twin 5 year olds share for some time. I realized using it as a frag overflow was not fair to this tank as it is still going strong and I first added water in August of 2004. I decided to clear some stuff out and perk it up a bit, putting a few things back in her ethat had been residing in my 60 display. I say I am much happier with the tank and glad it is still plugging along.
