I think almost in every Asian family, if you have a house big enough to have a small pond, you can almost always find a koi. Actually, the kohaku koi is just one type of koi in the Gosanke category, which is made up of the Kohaku, Taisho Sanshoku, and Showa Sanshoku. Most koi enthusiasts will mix the different kois together in one pond, just as long as you don't mix kois of sizes that are extremely different because smaller koi will most likely be eaten by bigger koi. They are not aggresive, very calming to look at if you sit near the pond they will come close to you. You can also touch them and sometimes they will suck your fingers.
They are somehow hard to take care of because you need a pond that is adequate for their size. You have to change the pond water at least every few months. You also have to keep an eye out on their health as it is common for them to get sick from bacterial infections.
But... it's worth it! :)
