Last year we got a dozen feeder goldfish for our backyard pond and took
them in to winter-over indoors (aquarium). Now its getting time to
bring them back outside. The pond temperature reaches 60 F daytime and
drops to about 55 F overnight (Minneapolis, Minnesota location). The
indoor aquarium temperature runs 65 to 68 F and has been for 6 months
now. Will it be safe to transfer the goldfish at these temperatures.
