I was very happy when I found my old photos. They are of poor quality. But, what is depicted in the first photo deserves special attention.
These pictures depict a fish tetradon Thai Tetraodon leurus. This fish is very funny. She has very sharp teeth, she is able to snack a snail shell, with ease. Many know that the tetradon swells, like a ball, if it is taken out of water, or in case of another danger. It is also known that this fish is poisonous. This is a relative of fish Fugu.
All this information is widely available.
The first photo proves that we do not know something about these fish. Nowhere did I find information that tetradone is able to breathe atmospheric air.
One day, in the morning, I went to my store and saw such a picture. Tetradon lay on the surface of the aquarium filter. He was just lying on the beach. So it looked. I managed to take one picture with my clamshell Motorola, after that he jumped into the water. Maybe he decided that now he is not a fish, but a frog? I do not know, but, it's very interesting to know.
