Bettas are tropical fish which require warmer waters...77-80 degrees.Depending on where you live you may or may not need a heater. Usually if you are running an A/c though you will need one. I would start off by getting a thermometer to determine what temperature your tank is without a heater. What size tank are they in? Maybe I can recommend some nice heaters.
