What can you say about a small plastic aquarium with fake, plastic fish powered by a USB cable other than cool? Maybe it's a waste of space. A wasted USB port. Or you might be concerned that all that water would spill on your desk.

Fear not. The USB Aquarium keeps the tank completely sealed. Even if you knock the thing over, it won't spill. Also, the device can either be powered by a AA battery or a USB cable.

A couple years back, I actually won the USB Aquarium sold by ThinkGeek as a prize at a user group meeting. My kids love to look at it. I find it oddly relaxing to stare at.

If you're a geek and looking for extremely low-maintenance pets, this is a great gadget to have on your desk. What do you think? Leave your feedback in the comments.
