Can platies live in cold water?

Platies are tropical fish that thrive in warm water temperatures ranging from 70°F to 80°F (21°C to 27°C). They can tolerate slight fluctuations but do not do well in cold water, as prolonged exposure to temperatures below 65°F (18°C) can lead to stress, illness, or even death. Therefore, it's best to keep them in a heated aquarium to ensure their health and well-being.
