so as a HUGE thunderstorm ripped thru my area last night, and I was checking off my mental list of what i needed to do if the power went out, I realized I HAVE NO IDEA WHAT TO DO FOR MY FISH!!! ACK Our power is pretty stable, but if we lose it, its a 5-12 hour deal. What do I need to keep my fish alive during an exteneded power outage? How long can I just leave the tanks alone without doing anything? (2gal, 5gal, 29gal)
