Introduction of Aquarium Heater

The work of an aquarium heater is just to provide the heat to the aquarium. An aquarium heater is all time needed equipment for all the fish keepers. It helps to maintain the required water temperature of the tank.

Aquarium temperature between the range of 75 to 78 degrees Fahrenheit is the best living conditions for your tetra fish. Some of the best aquarium heaters for your tetra fish are;

If the water bag is not hot enough, you can pour hot water into the bag and place it for some time in the aquarium. This method can work but is a bit unconventional, so using it only in an emergency is more preferable.

Shifting Tank in a Warmer place

Shifting your aquarium to a warmer place in your house is a good idea to maintain heat. Placing the tank bit nearby of the sun is fine but you have to avoid direct sunlight. As lighting is also a good way to create heat, placing a tank near or under some light is fruitful.
