Fishy, the issue of "butt wigglers" (fantail goldfish of all sorts) has been a discussion here many times, so far I've not heard of ANYONE that has had any babies. They HAVE to have babies, but Lou, if you are looking for pretty (they come in all colors - orange, orange and white, black/orange/white and all types, too!!!), and something that will not multiply, and love to be pampers, and very friendly, I vote for the fantail goldfish. Granted, you will have to buy them, but Santa could bring you a couple for Christmas maybe?! They are cheap if you buy the small ones, which is what I do, as I love to watch them grow. My fantails tend to be more "workers" as far as cleaning things, working on the bottom, etc. than the other Comets and Shubunkins I have. Just saying .... Good luck! I think you should definitely keep letting Cathy know we are not trying to encumber you with work or cost, just something pretty and playful for your enjoyment in your pond!
BTW, how did you lose your fish previously? I don't remember, was it predator or water quality or what? One more point, I think some of the fancier fantails are not as winter hardy if your pond freezes. I have several of the regular fantails (some short tailed, most long flowing tails) and they all did fine last winter. Bought some small ones this summer, will see how they do, but sure don't notice them slow down at all when the water temps got down to 40 earlier this month!
