Questionhi, I'v been wanting a heater for my 3.5 gallon betta tank for a while now, but the past 2 automatic heaters I have bought dont work! >:O So i would like to know if you reccommend any NON-AUTOMATIC heaters for samll aquariums. thanks,
Ann =)
AnswerI do not have any real recommendations other than the tetra brand auto heater, but if you really don't want that, You can keep the bowl in a warm (not hot) place.
I live in a very cold place, it's currently a scorching 3*F with wind and snow so in tank heaters are really the only effective option.
