Well, with all that's going on right now I haven't had time to look for the pipe. It appears that it might be hard to find. It seems like this is a good idea though, and different pipes might be useful. Those were expensive fish, but I got them when they were babies. First I'll try the goldfish, if they don't end up as dinner, then I will consider getting Koi again. It's probably good to have a lot of plants also, trouble is in the cold weather the plants die back. Oh well, back to the drawing board! :0 Arum
