The temperature should be kept at 75-80 degrees Fahrenheit. Colder water can kill the betta, as the betta's immune system will slow and make them susceptible to disease. Hotter water can make them uncomfortable and age quickly, as their metabolism will increase. The temperature should be maintained with a heater.

Absolutely! Bettas originate from Thailand where the average temperature is usually around 80 degrees Fahrenheit. So, you definitely want a heater especially if the aquarium is cold. Bettas are also more vibrant and active when placed in a heated and filtered tank.

As with any aquarium, a betta aquarium should be set up 24-48 hours prior to the first inhabitants being introduced. However, if you can stand to wait a week after setting up, this will even better ensure everything is safe with your filter, heater, lights, and water parameters.
