Ok, I've just recently set up a smaller 5 gallon tank than my 29, and I actually forgot to buy a heater for it. I had realized this after I had set the whole thing up and had everything else I needed in it. Everythings running fine, the fish in it is healthy, and I was wondering if I needed a heater at all, because the temp has been at 74F for a couple of days now. The only fish in the tank is my mosquito fish.
