Tips To Keep Warm Betta Fish Without Heater

Betta fish require a constant temperature of approximately 80 ℃ to keep fit and cheerful. The only approach to attain this is to use a 30-watt heater in a smaller tank of 4-5 gallons. This post was written for anyone who doesn’t have a heater and wants to learn how to keep betta fish warm without a heater.


#1. Room with heat

Apart from an aquarium heater, the most efficient way to heat a tank is in a warm environment. The environment will need to be quite heated, far above 80 °. This is not an issue in certain parts of the globe, although it can be challenging in colder climes. Continuous heating will be required in the room. One of the essential advantages of a heater is that it maintains a constant temperature in the water. 

Temperature changes stress bettas, and anxiety has a harmful influence on their immune system. Whenever a betta’s immune system is weakened by stress, they are more susceptible to sickness. Some temperature variation is okay, but not if it exceeds 1-2 ° Fahrenheit every hour. This would be possible to use central heating or individual heating systems in a single room. The betta might also remain in a room which is already rather hot, saving you cost.

Most dwellings have a range of temperatures, with certain places being chilly some being hot. The betta will flourish if the warm parts make the water around 79 and 81 degrees. The biggest issue with non-mechanically heated rooms is that they frequently lower the temperature overnight. Bettas require hot water at all times of the day and night; thus, rooms that chill off overnight would not be suitable. The most efficient technique is heating the space and staying warm using central heating.


#2. Lighting your aquarium

Though we all know, a sorbet cannot be left out in the sunlight as that will melt. Likewise, water exposure to direct sunshine would heat up faster than water in the vicinity. It’s why rivers and lakes appear hot on the top but contain frigid water beneath them. Keeping a betta in the sunlight is reasonable to keep the tank warm, but there are two significant drawbacks. The first is that the betta might boil if it gets too hot, and the temperature would most likely vary. 

The second problem would be that the warmth will be removed overnight, causing the fish to grow ill. Because the aquarium temperature is likely to fluctuate, you’ll need to keep an eye on it all the time. This approach is unpredictable and might change from week to week, and it needs more labor and upkeep than most others. You might be capable of supplying heat to your betta’s water using a submersible aquarium lamp if you do have an aquarium cover. 

Some energy is constantly wasted as heat energy, and no mechanical energy is 100% effective. As a result, aquarium lighting generates heat. When the aquarium has a lid, the heat created by the light could be sufficient to heat it. Underwater light is not required, but it will increase the aquarium’s temperature.


#3. Use warm water

The strategy necessitates ongoing attention and supervision. It was not a long-term solution, but it was pretty successful in the short run. If the electricity goes off, the heater malfunctions or you’re waiting for a heater to arrive, use this option. You’ll require hot water as well as a container that really can properly handle boiling water for this procedure. Glasses and ceramic cups are fantastic candidates because most food-approved materials are aquarium safe. Some dish detergents may cause an issue, so wash these with deionized water before using them.

Start by half-filling the mug, pitcher, or barrel with boiling water to use this procedure. Secondly, make sure there was nothing on one side of the tank weighing it down more than another. Put the water container on the base of the aquarium, making sure it doesn’t spillover. We wouldn’t want it to squeeze your small companion, so stay the hell away from the aquarium’s sides. Keep a close eye on the temperature reform to ensure it doesn’t exceed 2 degrees every hour. The most challenging element of this procedure is keeping the temperature steady, so you’ll have to replace the containers periodically.
