heaters mainly stabilize the temp in the tank.
drastic fluctuations can be harmful (stress the fish).
if you live in a climate in the tropics you may not have to use a heater very often.
even then it is probably stil a good idea to have a heater...IMHO
if you need a heater, get a printout from the internet with prces..the shop..I went to petsmart yesterday ..I took a printout of the stealth heater for $20.99 showed it to the cashier..she sold me the heater for 20.99..the price in the store....$36.99
