You can have white cloud mountain minnows in coldwater as well as tropical, but they are small, so you should probably get a sarasa comet or a shubunkin... (i cant spell, sorry)
I had a sarasa comet in this tiny tank and then found out it needed a large space so unless you have a big tank, do not buy one. They are very pretty though.

i went out and caught some small roach and gudgeon in a local pond and put them into my tank for something different, they will have spawned by now so there will be a lot of fry about in the margins, you can scoop em up with a net
