Small planted office tank

[likwid]

Hey guys,

I would like to set up a small planted tank for my office.. Something between 3-6 gallons. I am in a smaller city, and do not have many fish specialty stores to buy equipment for a tank. I was wondering if there was a tank I can buy from Petcetera, Walmart, Petland, etc that will be sufficient for a small planted setup. My main concern is the stock lighting and filtration. I would like to keep one dwarf puffer in the tank, which would require a lot of hiding places. Any ideas?
