Betta Water Too Hot
Even better being thermostatically controlled like your water heater they take much of the hassle of monitoring water temperatures away allowing you to enjoy your fish once more.
Betta water too hot. Hot water contains fewer oxygen molecules than cold water. If you re having ongoing issues with your betta fish water being too hot then investing in one or more of these cooling fans can be a very wise investment. However this doesn t have to be a bad thing.
As you re well aware a water change can often change the temperature in your tank causing it to drop to dangerous levels. They may start swimming erratically and their metabolism rate will increase. As stated before water that s too hot will affect the metabolism of betta fish.
As a result betta fish will start breathing rapidly or float towards the surface in search of oxygen. The low oxygen levels will hinder their respiration which will eventually damage their metabolism s rate. It will be cooking albeit slowly.
So 87 degrees fahrenheit and above is too hot for betta fish. If your water is getting too hot then try performing a partial water change of 5 10. You don t want to drop the temperature too rapidly.
Perform a water change. However if the water temperature in your aquarium exceeds 86 degrees your pet fish will no longer be surviving. You will see your betta hovering at the surface of the water gulping air in order to get enough oxygen in their system.
