This video may not be for everyone. If you're impatient person in a hurry, don't watch it. But if you're an impatient person and want to lower your blood pressure, watch it. I'm an 'A' type and this video calmed me waaay down.
No dialogue; has some repetition; the background music might annoy some, but simply turning the volume down solves that issue.
A fish expert probably has seen all of the fish before, but there were at least 6-8 species that I hadn't. And they are spectacular! The videography is truly excellent too.
Highly recommended because I'm sure to watch it a second time, which is a rarity for me.
