If you are asking if they can live in a cold outdoor pond than the answer is no. They come from a tropical climate in South America and are not meant for water below about 72' Fahrenheit (22.22' Celsius).
It can if the temperature doesn't get below about 72 degrees Fahrenheit which is very unlikely. So no they can not.
Pleco's are tropical fish, so if your pond has a sub-tropical temperature, the pleco will not survive in the pond for very long.
It isn't really recommended because it is a tropical fish but can live with koi if it doesn't get too cold.
In South America, where they come from, they all live outside. They would only be able to live outside where the temperature range is always warmer. I currently have one in my pond which he loves. Since he is a tropical fish I will have to bring him back inside when the weather turns cooler and the water temperature become colder.
An outdoor pond is appropriate for a terrapin because it is a suitable habitat for them. Terrapins are best suited for shallow ponds that are less then three feet deep.
what is the climate on a pond
The temperature of pond water is usually cooler than the temperature of the surrounding air.
No they will not survive the winter in most any place in the US if they are outside. They prefer the water to be from about 72-82 degrees Fahrenheit.
I can get an outdoor pond by digging on in my back yard. FIrst, dig a large hole, the shape of your pool and its depth. NExt, fill he hole with cement so it can take the shape of your pool. FInally, add water and you have yourself an outdoor pool.
Most likely.
The temperature of a pond can be measured using a thermometer specifically designed for aquatic environments. This thermometer can be submerged into the pond water to provide an accurate reading of the temperature. Alternatively, electronic devices such as temperature probes or data loggers may also be used to monitor the temperature of a pond over time.
There are many stores that sell outdoor pond cleaning items. One place to look for these items would be your local pet store, or maybe even a pool store.
