What dose a heater do in a fish tank?

A heater in a fish tank is used to maintain a consistent, appropriate water temperature for the fish and other aquatic life living in the tank. Different species of fish have different temperature requirements, so it's important to ensure that the water temperature in the tank is within the appropriate range for the specific type of fish you are keeping.

In general, most tropical fish need a water temperature in the range of 24-28 degrees Celsius. Coldwater fish, such as goldfish, may prefer water that is slightly cooler, around 20-23 degrees Celsius.

A heater in a fish tank helps to maintain a stable water temperature by using an electric heating element to warm the water. The heater is typically placed inside the tank and connected to a thermostat that measures the water temperature and turns the heater on or off as needed to maintain the desired temperature.

It's important to monitor the water temperature in your fish tank regularly and to adjust the heater as needed to ensure that the temperature stays within the appropriate range for your fish. If the water temperature gets too cold, the fish may become sluggish and inactive, and may be more prone to illness. On the other hand, if the water temperature gets too hot, the fish may become stressed and may also be more prone to illness.
