Typically heaters are needed for tropical fish tanks. However, if you could guarantee the room temperature where the tank is located will be maintained at the needed temperature for your fish, then you don't need a heater. Most tropical tanks need to be maintained at temperatures of 72 to 80 degrees Fahrenheit, depending on the types of fish in the tank.
One can purchase a fish tank heater at various pet supplies shops. PetSmart, Petco, Marine Land, and Argos all have fish tank heaters for sale on their websites.

Not all heaters can go inside a fish tank. The heater must be specifically made to be put in an aquarium. You can order one off the internet as long as it is made to be put in water or you can get one from your local fish or pet dealer. It would be better for a first time fish owner to get one from a pet dealer instead of the internet.

You meet and befriend a fish breeder who will take pity on you and supply you with a tank and fish and all the equipment needed to keep them. Or maybe you could just meet someone who has a tank and fish and doesn't want them any more and is happy to give them to you.
AS water heaters age, they corrode and also incur mineral deposits and sediment at the bottom of the tank. This sediment is what causes the popping noises when the heater turns on. It is mini explosions inside the tank. Having yearly maintenance on the water heaters helps to prolong your heaters from having this issue by flushing out the sediment buildup and replacing the sacrificial anode rods when needed.
