i use to live in a town 30 min from snow and people had gold fish in out door ponds.. ..sometimes iced over but definately got very cold and they all survived wonderfully.. bred like crazy ..
Ponds are one thing small tanks are another if it freezes solid the water expands and breaks the tank seals. What is there to do in Pittsburgh I am here working and my homes 900miles SW?
I've been out since I posted this pic...David, fortuneately the tanks are only $10 anf the goldfish are cheap too. Right now we Pittsburgers are tilling gardens (my asparegus is up), planting flowers and experimenting with fish on the deck :)
i had about 15 foam boxes outside with goldfish breeding in them to feed to my old fish i didn't do any water changes or anything they lived fine with the rain and just water tops up if it didn't rain
soon as it gets a little warmer those guys will roast,especially if it's not shaded,10 gal is too small of a body of water for outdoor living,especially with no aireation.:)Good Luck though!
John, my deck is well shaded. When it gets warmer, I hope to add some airstones to help with the oxygen transfer...just got to run an electrical circuit to the deck.
Congrats !If they are red zebras males are naturally blue, hatched brown, w
