What is aquarium heater? Which type of aquarium heater do I need? What and how many type of aquarium heaters are there? What should I pay attention to when buying an aquarium heater?
For many goldfish, heating is a necessity rather than an option. A large proportion of both saltwater and freshwater fish need a heated aquarium. Unlike humans, fish cannot balance and regulate their body temperature, so it is very important to have a heater in their aquarium.
Fish rely on the water they live in to maintain their body temperature in a balanced way. It is therefore important that your aquarium is constantly maintained at a constant temperature.
