I'm always on the lookout for unique and interesting goldfish art, and I recently stumbled across an awesome artist! His portfolio website is all in Japanese, and I don't know the first thing about the language, but here's what I could glean from it by using Google Translator. Kenshiro Iwata was born in the town of Hayama, Kanagawa Prefecture in 1979 and he graduated from the Ochanomizu College of Art in 2001.
Although I could only find a few details about the artist and his work, I think the images speak for themselves and they're really beautiful! My favorite of his images are those from a goldfish series done in 2011. Each image features a distinct goldfish variety (for example, a tosakin, redcap oranda, or a jikin) and a young girl next to the goldfish. The girl is styled in a way that reflects the shape, colors, and overall look of the goldfish she stands next to.

Here are a few of my favorites from the goldfish series!
He also has a few pieces that are, I think, a little more whimsical. Here are a few of them.
