The Happiest Fish in The World?

aquarium 001Once again the people who regularly contribute to the social news site www.digg.com, have found something that I dearly wish I had thought of myself.

These fish tanks run between two regular-sized aquariums, but based on the principle that ‘nature abhors a vacuum’, the fish can swim up and down the tubes connecting the tanks together. If you check out the other pictures at this link you’ll see various examples of them in people’s houses, restaurants and bars.

I heard on the radio recently that the theory that fish can only remember things for about 2 minutes had in fact been completely disproved (not quite sure how they worked that out). So these tanks should be a must-buy for anyone looking to maintain a mentally and physically stimulated fish.
