The Complete Guide to Aquariums
The word aquarium originates from the ancient Latin language, aqua meaning water and the suffix rium meaning place or building. Aquariums are beautiful and look good anywhere! Home aquariums are becoming more and more popular, it is a hobby that many people are flocking too and fish shops are on the rise. Fish are generally easy to keep although do they need quite a bit of attention. Puppies and kittens were the typical pet but now fish are becoming more and more frequent in house holds. In recent years fish shops have noticed a great increase in the rise of people wanting to purchase aquariums and fish, the boom has been great for local shops as the fish industry hasnt been such a great industry before now.
Working from Columbia's middeck, two technicians were lowered, one at a time, in sling-like seats down the 6-m-long tunnel into Neurolab in the payload bay. One technician waited in a shelf-like 'bend' in the tunnel, while the other entered the module itself to await the animal cages and aquariums that were then lowered on separate slings.
Elsewhere, a minor problem cropped up with the four oyster toadfish on board Columbia. They possess gravity-sensing organs reminiscent of human inner ears, and although each had been fitted with a small transmitter before launch to monitor neuronal activity, the signals were found to be intermittent, possibly due to an electrical fault or problems with the oxygen-circulation pumps in their aquariums. Nonetheless, Stephen Highstein of the Washington University School of Medicine said, ''We think we can achieve 100 of our science goals even with intermittent data.''
