Mini Tank Heater...
I recently bought a mini tank heater for tanks/aquariums of 2-10 gallons. I have a betta who is in a 2 gallon bowl-he's very healthy..swims quickly, eats fast, seems to be very curious. But I was having issues with water temperature, so I bought this mini heater to raise the temperature by a few degrees.
The heater raises the temperature very slowly, and not by too much- only about 3-5 degrees. The only concern I have is with keeping it on for a long time- even overnight, which i have not done. I've only used it for a couple days now, and only for maybe a couple hours at a time. I don't want my fish to experience fluctuating temperatures, but also, I don't want the bowl to overheat if the heater's left on.
Does anyone know if it's safe to keep a mini heater on overnight? If not, any suggestions on keeping a 2 gallon bowl warm enough?
