Just as salmon are accustomed to cold water temperatures, several Florida fish like tilapia and peacock bass are acclimated to warm water temperatures. So, if we have a cold snap that lowers water temperatures below 55°F, entire populations of these non-native tropical fish will die-off.
What temperature is too cold for fish?
Cool water fish do better in temperatures below that, usually between 60° and 75°F (15-24°C), but some of them enjoy water well below 70°F, which is not suitable for any tropical fish. Ultimately the best temperature will depend on the species of fish in the aquarium.

What temperature is the danger zone for fish?
The temperature range at which disease- causing bacteria grow best in time/temperature control for safety food (TCS) is called the temperature danger zone. Temperature danger zone is between 41°F and 135°F. TCS food must pass through the temperature danger zone as quickly as possible.
What temperature can freshwater fish survive?
A good range is 76° to 80°F (25° to 27°C). A few species need to be kept several degrees warmer, and some species require temperatures a few degrees cooler. A thermometer is vital. A stick-on type enables you to check the temperature whenever you look at the aquarium.

Boiling creates bubbles that contain dissolved oxygen. When boiling the water the dissolved oxygen present in the water decreases. An increase in temperature results in decreased levels of dissolved oxygen in the water. This can harm aquatic animals such as fish, amphibians and other aquatic organisms.

Can fish survive bottled water?
Not exactly. Bottled water is typically either well water, filtered water or spring water. It may have gone through filters that remove some of its beneficial components, or it may have extra minerals that are unhealthy for fish. You would need to test and adjust it before using it in your tank.
