In video, there are cichlids, result of releasing aquarium fishes in local water bodies.

Yes, absolutely right, you have many biotope in the world who are in danger because of invasive species.
The people do not know because the trade in wild fish is sharply down. Consequences people forget the diversity and therefore they also forget the biotopes.

It was also a lack of responsability toward the biotope. People do not understand that preservation of habitat, it is important.
