I've been looking around for a small heater for the 2.5 gal tank I'm setting up. Fortunately, right now we are having unseasonably warm weather, but eventually it will cool off and I'll need something to keep the temp from fluctuating. I saw a small heater at Wallmart that was for small tanks, but it had no way of adjusting it. It just said to unplug it when the temp reached 82!
I think it was 7 or 7.5 watts. A heater I couldn't set was just too scary to consider.
But I've looked around LFS and so far haven't seen any low wattage heaters. So, how do all of you heat your tiny tanks?
