For most of the time its typically people misguided by the fact that if one is good then two must be better, which is true to a point but it can be harmful if you don't understand the processes at work, two power filters on a small tank > 40 gallons can actually create too much flow for certain species of fish. As far as I'm concerned, only thing need for filtration on tanks smaller then 50 gallons is a sponge filter and lots of healthy live plants to soak up the nutrients.

It comes with a lighted hood, a small packet of sample fish food, an undergravel filter and a small air pump. You will need to get some other items as well for your aquarium. As mentioned previously, a small tank can be more work than a large tank because you really have to stay on top of those water changes to prevent the small aquarium from becoming too polluted.
