Tetra or the Tetra Werke (Company) is a fish food manufacturing company founded by a young German scientist, Dr. Ulrich Baensch.〔(Tetra Werke Company Profile (U.S. Website) Spectrum Brands, Inc., Blacksburg, VA, U.S.A., date retrieved: 28 May 2007 )〕〔Hermann Simon mentioned this company in his correspondent Book as an example of a "Hidden Champion" (Simon, Hermann: Hidden Champions of the 21st Century : Success Strategies of unknown World Market Leaders. London: Springer, 2009.- ISBN 978-0-387-98147-5.)〕 ==History and profile== In the 1950s, there were only about 50,000 fish keepers in Germany and the hobby was, at the time, considered as traditionally very time-consuming, rare, difficult and complicated because it required routine collection of live food from streams and river beds, until the invention of dried flake food (''Tetramin'') for tropical fish by Dr. Ulrich Baensch. Baensch's ''Tetramin'' fish food consisted of four different type of flakes and vitamins. The brand name ''Tetramin'' was derived from the Greek word ''Tetra'' (meaning ''four'') and the third syllable of the word vitamin.〔 (Tetra Werke Company History and Profile, Tetra - Partner for Fishkeeping and Ponds, Tetra Germany Website, Tetra GmbH Herrenteich 7849324, Melle, Germany, date retrieved: 28 May 2007 )〕 The invention of ''Tetramin'' flakes, in its trademark yellow tin and brown lid, allegedly changed the fishkeeping hobby from a minor aquatic specialty into a favorite of millions of enthusiasts all over the world, thus making ''Tetramin'' a supposedly notable brand of fish food and Tetra Werke as a self-proclaimed globally recognized company in the industry, earning international affiliate.〔 The Tetra group employs over 700 colleagues, has representatives in more than 90 countries worldwide and is the largest manufacturer of aquaristic and pond products in the world. Apart from pet food, Tetra supplies fish keepers and pond owners with other products such as water conditioners, plant conditioners, technical equipment and medicinal products.〔 It was once a part of Warner-Lambert and was later acquired by Pfizer. In December 2002, Pfizer sold the Tetra aquaristic and pond business to the "Triton Fund", a private independent European investment fund. Investors in the Triton Fund include European insurances and banks as well as significant American institutions. The Triton Fund paid $238.5 million US for the Tetra business. Three years later, on April 29, 2005, Tetra Holding GmbH was acquired by Spectrum Brands, a global consumer products company.〔("Company News; RAYOVAC to buy Tetra, German Maker of Pet Supplies", New York Times, March 16, 2005 )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tetra (company)」の詳細全文を読む スポンサード リンク
