Does the water need to be heated for a fighting fish?

fighting fish can be in temp. 70 - 80 no higher or lower and use tap water do not use bottle water fish live longer with tap water I had made that mistake by using bottle water fish did not live to long tap water fish lived over two years also if your home is warm you don't need to have a heater room temp. is fine for fighting fish If you live in a tropical, warm place like Singapore or Jakarta then no heating is needed! If you live somewhere colder then try buying a heater. Don't buy an oxygenator though it's a waste of money since they don't take air from the water but from air.

My Bettas can live in either warm or cold water but recently I noticed that when I put a flat heater in the tank he would stay snugged against it.
