Sorry for all the questions guys. I'm just really frusterated right now having 3 fish tanks in my teeny tiny room. Ok so is there any kind of heater that you don't have to plug in or anything else you can use to heat the tank without plugging it in? I can't have too many plugs plugged in in my room. I already have 5! Heater for 10g, filter for 10g, light for 2g, light for my room, and another lamp. I don't need anymore! Thanks.
