Well, I love fish tank, specially salt water fish tank. But it is time consuming and cost too much. Well here is sort of solution.

Supposely a really popular item in Japan is the Aquapict Jellyfish Aquarium. It displays color-changing jellyfishes (see video above). The system includes a 5-color LED lighting system that has red, yellow, green, blue and purple). They move with the slow current in the tank like the jellyfish aquariums. But they are not real, but they look like real.

Specifications:
• Height: 270mm (10.6in)
• Width: 210mm (8.3in)
• Depth: 120mm (4.7in)
• Aquarium material: High quality ABS plastic
• Jellyfish material: Silicone
• Power: AC adapter

It will cost you $155+$39 shipping to US. Kinda expensive but it will be coolest desk gadget in your office.
