So, I have a 1 gallon bowl that I'm in love with, but every time I house a betta in it, I end up rehoming it within a day or two because of the heating situation.
So I was curious - for those of you who have 1 gallon tanks, how do you keep the temperature steady? My frustration is that all the one gallon heaters i've seen only have two settings: ON and OFF. I'd like to keep a betta at work in a smaller 1 gallon, but our building is lit by skylights...which can get extremely hot. I'm actually concerned that the water will get too hot. I have a hydor 50 watt, but it won't fit in a 1 gallon. what do you guys do for a 1 gallon?
