    Hi all,
    We live in Florida and have an outdoor pond. Obviously, the pond never freezes, but in the winter, we can get below freezing at night, for several nights in a row. Last winter was a cold one!! We had plecos in the pond, and they all died over the winter - we assume from the cold. The goldfish, however, loved it.

    My question is - what is the lowest temperature a pleco can live in? And would a large aquarium heater used on very cold nights be enough to keep a 450 gallon pond warm enough for the plecos? We don't want to warm it up too much, just enough to keep the plecos happy.

    Plecos are not a good choice for ponds. Their temperature range is 73 to 82 degrees F. When you had freezing temperatures, your pond probably dropped below 50 degrees F.
    High Fin Sharks are a much better choice and I think you might find thye cost less.
