Fishkeeping revolution

In 1951, the natural scientist Dr Ulrich Baensch registered the company Tropenhaus (later Tetra) in Hanover. Two years later, he founded the BioMin laboratory, where he was able to test and further develop his products. During this time, he introduced many innovations to the market and applied for several patents.

Developing the brand

In 1962, the company headquarters with around 20 employees was moved to Melle and renamed Tetra Kraft Werke. At that time, Dr Baensch had already registered 15 patents for manufacturing processes and 20 trademarks. The company also published its first aquarium magazine, Die Wasserfloh-Post.

Globalisation

At the beginning of the 1970s, production was expanded to the new site in Offelten. Tetra then had about 420 employees. At that time, the first Tetra expedition to the Amazon was undertaken. In 1974, the company was sold to the American group Warner-Lambert, thereby taking its first step towards globalisation.

1980s
Pond Sticks
Conquering garden ponds

At this time, garden ponds were becoming increasingly popular and Tetra presented Tetra Pond, its first complete product range in the garden pond sector comprising food, care and technology. The innovative Pond Sticks float on the garden pond’s surface so that you can watch the fish eating undisturbed.
