You're saying; "What? He arranges goldfish and water plants in strange containers creating surreal goldfish environments?"
You think that's goldfish you're seeing now? Hmm...
No, he paints a layer of the goldfish, adds a layer of resin and paints the next layer of goldfish. Even when you know how he does it, your brain won't let you believe it.
He even includes what looks like fish droppings in some of the containers. Below are two images of a larger piece and I have included a video of how he made it. I think these works of art are extraordinary and wonderful and at the same time tranquil. Ryusuke Fukahori's web site is here.
