Rice Fish?

Question
Help,
about twenty years ago I had a coldwater aquarium and along with my moors I had somthing I recall as being called "rice fish" . these were about 1/4 inch in length, fully grown, and orange in colour. I have tried all my local aquarium places and they all think that I am mad. I have also tried an internet search but all I get is recipies for rice and fish, or fish that live in rice paddys. please help I would like to find out about these fish (scientific name, etc.) and possibly a stockist.
I hope that you can help or direct me to a website that can. thank you for your time.

Hi Paul;

These little fellas go by several common names but their scientific name is Oryzias latipes.

Common names are; medaka, Japanese killifish, ricefish, medaka ricefish, Japanese medaka.

Here is an interesting page about these fish being used in the space program. They were the first vertebrates to successfully breed in space in 1994.
