So one of the things I haven't gotten yet is a heater. I know living in Maine, we definitely need one, especially for the winter.
Right now, the betta is being moved in to a 5g tank. We are probably going to put a couple tetras in with him for company and tank ecology.
Inevitably, I feel like we will be going larger, and getting a 10g tank at some point.
My question is really this ...
Should I get the 50w heater that the low end rating is for 5g tanks and the high end is 14g.
Or should I get a 25w with a 2g-7g rating?
They are the same brand heater, adjustable, and fully submersible.
