What kind of water does my betta need?

You can use tap water for bettas as long as you dechlorinate it. Ensure that it is at room temperature, because that's what it's going to be in, a bowl sitting in your room. Also, you can use bottled water that doesn't have any chlorine in it to begin with, as long as it's room temperature. Temperature with everything is critical, so you want to match that temperature. Fish can't regulate their own temperature.
