If you are keeping tropical fish, you will need a heater. The tank doesn’t get too cold, and the temperature stays the same during the day, even when the room cools off. The temperature of 78F is a good starting point for many tropical fish. If your tank is too cold, your fish will not be able to keep up with the heat and will die.
A heater can be purchased from a fish store, or you can build one yourself. You can also buy an aquarium heater from your local hardware store for about $10.00. The heater will have a thermostat built into it, so that it will keep the tank at the correct temperature for the length of time that you want it to be.
It will also have an automatic shut-off valve that will shut off the heater when it reaches a certain temperature. This will prevent the fish from overheating, which can cause them to die of hypothermia (i.e., death from lack of oxygen). If you don’t want to build your own heater, there are a number of commercial aquarium heaters on the market that are available at most hardware stores.

Do you need a heater for a freshwater fish tank?
Freshwater fish tanks need heat or not according to the type of fish being kept. Some freshwater fish are more sensitive to heat than others, and some species can’t tolerate cold water at all.
Does a 5 gallon fish tank need a heater?
If you have a 5 gallon tank, you don’t need to spend a lot of money on a heating appliance. They’re not needed in smaller aquariums. Some of them wouldn’t be able to fit in a 5 gallon tank, or would take up a lot of space.
If you’re looking for a heater that will last a long time, this is the heater for you. Rated 5 out of 5 by HomeDepotCustomer from This is a great heater! I purchased this heater to replace an older one that I had. The new heater is much more efficient than the old one. I am very happy with this purchase.
Can fish get burned by heater?
It is at best a rare occurrence, and more of a case of proximity than design, that aquarium heaters can burn fish. I think it’s more of a case of proximity because for a fish to sustain burns, it must be pretty close to the heater for at least a few minutes.
If you have a tank with a lot of fish in it, you might want to consider adding a heater to your tank. If you don’t have any fish and you’re just starting out, I’d recommend getting one of these. They’re cheap, they’re easy to use and they last a long time.
What fish can live without a heater or filter?
The common fish species that are suitable for life in an aquarium without a filter are: Bettas, Guppies, White Clouds, and a few others, sometimes joined by other species. Bettas are the most commonly used fish in aquariums. They are easy to care for and can be kept for a long period of time without any problems.
However, they are not the best choice for beginners, as they require a lot of attention to keep them healthy and happy. The best bet is to choose a fish that is a good match for your aquarium and that you can keep for at least a couple of years.
Can betta fish live without a heater?
Bettas are tropical fish and people don’t often think of them that way. In the wild, they live in warmer water. They need temperatures between 70 and 80 degrees. If your room temperature is consistently in the mid-70s at the lowest, you’re probably a betta.
Bettas can be found in tropical and subtropical waters around the world, but they’re most common in temperate waters, such as the Atlantic, Pacific, and Indian Oceans. In the U.S., there are more than 1,000 species of bettis, with the largest population in Florida, according to the National Oceanic and Atmospheric Administration.
Are Bettas cold water fish?
Betta fish are tropical fish. This doesn’t mean you have to keep your tank at room temperature. Bettas can survive at room temperature, but they will more than likely be stressed and prone to getting sick. The misconception of betta fish being tropical comes into play here.
Tropical fish do not need to be kept in a tropical tank. However, if you are looking for a tank that is more tropical, you may want to consider keeping your aquarium at a lower temperature and/or a more alkaline pH.
