Tetra Pak is called Tetra Pak because it was founded by Ruben Rausing in 1951 in Lund, Sweden. The name "Tetra Pak" comes from the combination of the Greek word "tetra," meaning four, and "pak," short for package. This name reflects the company's signature packaging technology, which involves creating a carton with four sides, making it easy to store, transport, and pour liquids. The Tetra Pak carton has become widely recognized and used for packaging various liquid products such as milk, juice, and soup. **

Ultimately, the distinction between commercial and freelance artist can vary depending on the individual artist's business model and approach to selling prints. **

Tetras are egg-laying fish, so they do not get pregnant in the same way that live-bearing fish do. However, female tetras can become full of eggs and appear swollen or round in the belly area. This is a sign that they are ready to spawn. If you notice a female tetra with a noticeably round belly, it is likely that she is full of eggs and ready to lay them. Keep an eye on her behavior and the presence of a male tetra displaying spawning behavior to confirm if she is ready to lay eggs. **
