Heater for 12g Nano tank?

[missnano]

I just got my New Nano tank. I was reading the insert and saw it did not include a heater. Do i need one.. if so what kind should i get. I looked at heaters and saw a whole wall of them
Thanks guys!

I personally like the hydor heaters. For 12 gallons I would go with 100W.

i use a 75 watt stealth heater in my 12g (rule of thumb is 3+ watts per gallon) it fits perfectly in my pump chamber so i dont have to try and put it in one of the other ones
