Early birthday gift for the wifey

As a early birthday gift for my wife I picked up, at a thrift store rate of course :-) a 40 gallon fish tank. It came with the base, tank, lid, light, filter system, and several air pump supplies. After a little bit of cleaning and then picking up a few guppies she is loving the new aquarium. She has been sitting there for a good while just watching them swim around.
