Kelly the thing is usually the air temperature here is hot enough so that the water is a good temperature without having to have a heater in the water. I have a thermometre which I check it with, but yeah. Norally it is not an issue.
I have checked around at fish stores and such and all the heaters I have found are $30+ I know that's not really much money, but I don't have that much to spend on something which would only be necessary on a few occassions, y'know?
And no 1fish2fish- we don't have walmart, and the local equivalents don't have anything near the range of products that walmart has. I've also checked on craigslist/trading post online and there is nothing in my local one that would be appropriate for the tanks what I have.
I do my best... I really do.
