Tepid Water Fish

Some fish species will tolerate cooler temperatures experienced in unheated indoor aquariums. These are generally hardy species from temperate or subtropical climates. Not all these species mix well with each other or with Goldfish, and we recommend you research your species well before choosing to purchase.
The species listed will usually tolerate temperatures down to 16 degrees Celcius, we recommend that you have an aquarium thermometer, and are aware of the minimum temperature of your aquarium prior to fish purchase, due to the vast range of ambient house temperatures.
