Betta fish really are some impressive fish to have in your home. These things look gorgeous, they have outstanding personalities, and they are really fun to watch. Fishkeeping is a fantastic hobby that we would not trade for anything on planet earth. However, just like with any other creature out there that you can keep in your home, there are a certain number of things you need to do to ensure the health of your betta fish. One of the most important things to be on point with when keeping a betta fish is tank temperature. Let’s talk about betta tank temperature and why it is so important for their health and happiness.
Why Is Tank Temperature Important For Betta Fish?
The temperature of the water your betta fish is in is very important because they come from a warm and tropical climate, mainly Thailand and Burma. This means that they are used to being in warm waters, preferably between 78 and 80 degrees Fahrenheit (you can get a stick-on thermometer like this one to easily monitor the temp). These fish come from places where the climate is very steady and temperatures do not fluctuate all that much, especially water temperatures, so this means that betta fish have gotten very accustomed to a specific temperature range.

It the water in a betta tank is any hotter or colder than the survivable range, then your betta fish will start to display some weird symptoms and even die. Keeping a betta fish in waters that are not of an ideal temperature can result in erratic swimming, floating on one side, reduced metabolic function, and a critically weakened immune system.

Simply put, if the water is too cold, you will freeze your betta fish to death, and if the water is too warm, you will cook the betta fish, more or less. Just imagine standing in a freezer for an hour, then standing in a giant oven. It would certainly not be comfortable and could definitely result in death.
What Is The Ideal Betta Tank Temperature?
So what temp should a betta tank be? well, the ideal temperature is very strict and it is between 78 and 80 degrees Fahrenheit, or 25.5 and 26.5 Celsius (using one of these is an easy way of keeping an eye on the temp). Now keep in mind, this is the ideal water temperature in which betta fish will thrive and do the best they can. Betta fish can survive in waters between 72 and 86 degrees Fahrenheit, or 22.2 to 30 degrees Celsius, but they will only be surviving instead of thriving.
Your betta fish will be the healthiest and happiest if you keep the temperature at the ideal range, but keep in mind, and lower or higher than the limits of the survivable range and your betta fish will quickly deteriorate and die. Keep in mind, these are tropical fish, so ideally they should be kept in fairly warm waters.
What Is The Maximum Temperature A Betta Can Be Kept At?
The absolute maximum temperature that your betta tank can be at is 30 degrees Celsius or 86 degrees Fahrenheit. Any higher than that and you are more or less cooking your fish, cooking it slowly, but cooking it nonetheless. You will notice weird behavior in your betta fish if the water is too warm. First of all, they will begin to be erratic in their swimming as well as overactive, or in other words, they will swim far more, faster, and in different patterns than in water of ideal temperature.
After a prolonged period of time, this may cause stress and death, plus their immune systems will also be weakened. At any rate, having water that is too hot is definitely not good for the physical or mental health of your betta fish.
What Happens If you Put A Betta In Cold Water?
If you put a betta fish in cold water, the first thing that you will notice is lethargy and a loss of appetite. This is because cold water will slow down a betta fish’s metabolism, thus causing it to eat less and have less energy. Moreover, cold water will make them susceptible to illness due to a compromised immune system. Finally, water that is way too cold will effectively cool down your betta fish to the point of freezing, pretty much like hypothermia for a human being.
Should I Get A Heater For My Betta?
A heater for your betta tank is something that you can consider getting, especially if the temperature in your home is room temperature, which means that the water in your betta tank will definitely be below the ideal range. If the water in your betta tank is anywhere below 24 degrees Celsius, you should get a heater and make sure that it heats the water to the ideal 25.5 degrees Celsius which they like to live in.
Try not to get a heater that is cheap because they tend to be unreliable in terms of heating the water up to a specific range, they may overheat the water, and they may short out and electrocute your fish too, all undesirable things to say the least.

If you are going to have your own betta fish you definitely need to keep in mind everything that we have talked about here. Temperature is very important and keeping your betta fish in water that is either too hot or cold will not be good for their health and can eventually cause death.
