열대어가 바글 거리던 한국의 강에 놀라운 변화가 찾아왔네요 [오브리더]

Hello, this is Obreader. Every year, I go fishing to observe the changes in the Guppy Stream. The guppy population has always fluctuated depending on environmental factors like weather conditions. However, this time, the Guppy Stream I visited was unlike anything I'd ever seen before. In a place where South American tropical fish used to teem with them, finding guppies has become incredibly difficult. Even when there were no guppies, this is the first time I've seen this much. And in place of the guppies, this familiar creature was bustling about. I'll show you the sight of these creatures, which were more abundant than I'd imagined, and the current state of the Guppy Stream.
