they are beautiful fishes...
they can be touched calmly aren't they?
Some of them can be touched kim, but mine seems to be easily startled. I think the pond that we have is too small to allow them to meander around as much as they would like to. But certianly I have seen kois which are calm enough for you to stroke their tops while their swimming by. I don't think this is very common though.

They look like they would be yummy in a nice seafood soup.
Are these fish for eating? Or merely decoration.
Oh no no comradejing. Most people don't really eat them. Like BananaMaster rightly said, they are collectors's items. There are numerous koi shows organised worldwide, and the ones organised in Malaysia get interest from many other neighbouring countries like Singapore and Thailand, and vice versa. Whenever any of our koi dies, we bury them. Nothing to freaky or spiritual, it's just practical to let them decompose and nourish the earth.
There are many many kinds of Japanese carps, and certain classification has been givem according to their colour pattern. Some of the more famous ones include kohaku, sanke, showa etc. The basic colours are red, white and black. There are other colour variants. My favourite is the combination of red white and black, which means they are mostly kohaku and showa.

A sanke
The photo that I attached earlier was taken at my uncle's house. He has a big collection of kois and as you can see he collects many kinds of coloured koi. The ones in my house are mostly kohaku with some sanke, so there are mostly red and white with some black thrown in. The photo I found on the net below reminds me a lot of the koi pond I have at home.
