Sometime back we enthralled your brains with the world’s largest privately-owned jellyfish tank. Now here is a chance for you to have one of your own, for $2,900. Although unlike the aforementioned aquarium, which could accommodate up to 150 moon jellyfish, this one is a more modest version, with just 10 allowed at one time. You could perhaps cram in more, but that would not then be such a pretty picture. This aquarium, called Monaco, comes with the additional option of color LEDs, making your home look like an underground sea lounge. So this could be one of those crowd-wowers for your next theme party.
