Actually, a Shubunkin/Comet mix would still be very nice. Shubunkin simply means tri-colored, Comet is a bi-color (red/white) fish. Otherwise, they can have same body style, if I understand it correctly. I have both in my goldfish pond, but have added more Shubunkins, as I prefer the tri-color mixture. Also, odds are if you buy from a local pet shop or Wal-Mart, and you get only Shubunkins, they may likely have Comet as a parent! However, if you purchase them from a breeder, you would have all Shubies for babies. I totally agree that if you like the Shubies, and the red/black with white spots one in your first pic is gorgeous, stick with them. In that size of pond, any babies you have out of 10 adults will need to be moved, IMO, so if you have friends that like Shubunkins over Comets, keep it to the same color. If you like diversity, go with both. Most importantly, have fun! :blueflower:
