[2][3] 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.

[4] 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.

Investors in the Triton Fund include European insurances and banks as well as significant American institutions.

Three years later, on April 29, 2005, Tetra Holding GmbH was acquired by Spectrum Brands, a global consumer products company.

[5] The Tetra Company was heavily criticized by the marine fishkeeping community after its appearance on Good Morning America in which it claimed that one of its kits, a 10-gallon (37.3 liters) aquarium and filter, could support the fish from Finding Nemo (a Regal Tang and Ocellaris Clownfish).
