that tank in the video looks ridiculously packed but for some reason all the fish look nice and healthy. the owner might have just put them together for the video...
Amano is my idol, he makes a living out of having fun (I would assume).
I could never do anything close to his tanks, one thing is to set them up and aqua scape it the way he does it, but to maintain and let them grow better with time is just amazing.
I wish I could make a living out of aquascaping, I can't picture myself getting bored
