Keeping pets in the office is probably not that popular with the boss but surely they can't argue about a couple of trouble-free jellyfish in a fish tank on your desk.

This little aquarium is powered by the USB port on your PC and when plugged in the high intensity light comes on illuminating two little jellyfish that will delightfully dance about the Aquarium hopefully bringing a bit of life to your desktop.

Even if you don't have a PC or want to have the aquarium elsewhere, you can add four AA batteries to power it.

Comes complete with two jellyfish and USB lead, just add water!
