There are "Neon" Barbus conchonius around with that odd coloured metallic look, these appear under a typically creative number of common names. At the end of the day, there is only one species, and 2+ human made sports which you either like, or hate.
There are "neon" Golden Barbs around as well, they have that coloured metallic look to. They look so artificial, I can't understand why anyone buys things like that.
