these are pretty good tanks, 7 yrs ago my daughters friends were using live feeder goldfish for table displays at their highschool graduation, I woudn't allow it , they returned all the fish except for 3 sick ones, I kept them in a 16 cup measuring cup while giving them daily treatments *L* once recovered I grabbed the cheapest bowl/aquarium at walmart I could find, not thinking they'd live very long....in May it will be 7 yrs they've been "swimming" in my kitchen. This may be a good set up for in your office(desk) I clean it once a month, it has an air stone, light for heat and a nice quiet hum to the pump. My dad raised fish for pet stores decades ago and I grew up with dozens of aquariums in our basement and swore I'd never have fish *LOL*....
