What happens if my betta fish gets too cold?
When the betta tank temp is too low, betta fish will become lethargic. Even if you put food in the tank, they may not go after it quickly, nor will they eat as much. You are also likely to see slowed gill movement and very little fin activity. In bettas, it is likely the fish will move to the bottom of the tank.
Can I add hot water to my fish tank?
Yes, you can. Using hot water to clean your tank is actually better since hot water is more effective at removing algae and dirt. Just make sure to avoid using hot water when cleaning the filter.
