without heating? Betta needs to be heated in winter. Because betta is a tropical fish, the temperature in winter is also very high when it lives in the wild, so it is better to install heat preservation and heating measures if it is raised at home. Betta fish generally have no problem living in water above 20 degrees, but when the water temperature is below 18 degrees, they will begin to reduce their activities and be depressed. When the water temperature is below 16 degrees, they will sink to the bottom of the tank to keep warm, stop swimming, and stop eating. When the water temperature is below 12 degrees, they will suffer from anxiety, shortness of breath, jumping and even shock. In this state, many fish friends will think that they are sick, but in fact, it has a lot to do with the water temperature. When the water temperature is around 10 degrees, most bettas will die. So in winter, you'd better heat it according to your indoor temperature.
keep the fighting fish warm in winter 1. Indoor: If there is heating in the room and the room temperature is above 15 degrees, there is no need to take measures to keep warm, just deal with the feces and food residues in the fish tank frequently.
2. Outdoor: If it is an open-air fish pond, it is better to add a thermal insulation shed or deepen the water level so that the fighting fish can warm up in the depths. If it is an outdoor fish tank, it is better to wrap it around with insulation cotton or foam board, and seal the top to prevent the temperature difference between day and night from freezing the water in the fish tank.
