These are not real fish! This is a photo of a 3-D sculpture, 3-D fish painted with resin "swimming" in resin! At first, when I heard about this style of art, I was confused, I thought that the images I saw were just photographs, but they are actually hand-made realistic goldfish! You can find out more about this if you check out this article: www.designboom.com/art/riusuke… The style was created by Japanese artist Riusuke Fukahori; you should read about him, its amazing!
I thought this was a photograph until I looked more closely at the comments! This is spectacular. The fish seem to be moving, and the reflection on the water is stunning. You have an amazing talent; keep it up!
The box isn't a painting, though! This is what he does: Gets a box, fills it with some resin, paints a layer of the fish, then adds another layer of resin, paints another part and so on. This makes an awesome 3D effect. o u o
