The AV100 Deluxe Tabletop Aquarium is certainly an interesting addition to any home, giving your fish an environment that is by far more interesting (to both parties) than the standard, cliched fishbowl. This 2.4 gallon tank looks somewhat like a flat screen LCD monitor (and could probably fool some people as a screensaver from afar) and features integrated filtration and LED lighting. You can choose from different color frames, while the background picture can be swapped depending on your preference. You can’t rear too many fish in each AV100 Deluxe Tabletop Aquarium though as the living space is pretty limited. Each of these retail for $150 and makes for a great home improvement idea.
