I just built a 750 gallon pond and have 9 goldfish in it. Considering it
gets very cold here in Montreal I will be bringing the fish in for the
winter. My question is how big of an aquarium do I need for these fish?
They were bough in June as feeder fish and the biggest is now no more than 3
inches long. I have a 10 gallon tank I could use. Is this too small? Any
suggestions?
