Banggai cardinalfish, native to the Banggai Islands of Indonesia, are becoming endangered because of unregulated and heavy-handed exploitation for the aquarium trade. About 10 years ago, they were introduced to Lembeh Strait, about 250 miles north of the Banggai Islands, where divers can regularly observe the fish, and their interesting reproductive behavior, mouthbrooding.

Compliments for the quality of your film. However, I think the invasion is not so beautiful. As can be seen in my own video about this invasion, the Banggai cardinalfish chases out some other species out of their anemone or sea urchin. In fact, this can be seen in your own video as well.
Best regards and good luck,
