You need to buy a heater and temperture controller.

Your best bet is several small heaters hooked to a RANCO or similar controller. All aquarium heaters are junk, and are very prone to sticking ON. Many people will pop and and say "I love my so and so..." but if you do a bit of research you will read dozens of horrow stories for every brand of heater. Spend the ~$100 on the controller and sleep well knowing you will not wake up to cooked fish.

finnex has gotten some good reviews. i would not reccomend WON.
i would also get 2 heaters that are undersized individually but good when used together. this will help minimize the chances of cooking your fish.
