The following documentary about freshwater fish of the Pilbara region in Western Australia water. Is a great accomplishment using modern techniques such as slowing down, acceleration, time lapse, use of drones and great underwater images of very high quality. And speaking of quality is recorded at 1080 so if you have that option, configure it to see so worth it.
Moreover species are not well known, if they appear for example Melanotaenias or Hypsseleotris. What it is interesting to see are the varied habitats that are appearing, some very rich in flora and crystalline waters.
No more I leave you with the documentary, enjoy it.
