My neons are all over 1" nowadays. I was at my LFS though, and they had what were labeled as Dwarf Guppies, they looked guppyish, and had unbelievable colors. I had to ask the guy if they were painted or engineered...he claims they are not. Anyways these little guys had a max size of about 1/2 inch. I was temped to set up a minitank for them, for my desk at work.
