I agree with you, nreimer. Guppies are tropical fish, but they are actually quite temperature tolerant.

As a child I used to catch guppies in one of the Dutch canals, not exactly a place where one would expect to find them. The location was an industrial area in the town of Delft. The canal in question was being used for cooling heavy machinery and therefore would stay warm and never froze over during winter. Now apparently some joker had emptied a guppy tank in there and if you know anything about guppy birthrate you can guess what happened. At times there were so many that food supplies got kind of low. So I would simply toss in a slice of bread, which in no time would be covered with hungry guppies, some even jumping on top of it in their feeding frenzy. Then all I had to do was scoop them up by the dozens.
