wow man, thats a great story! I was moving once and shut down a tank, long story short, I left two inches of water in the old tank for three weeks while I moved because I thought I hdad gotten all the fish out of it. Anyway, I got to clean it out and something starts moving around, it scared the hell outta me, turns out a pleco was still in there livin all three weeks in this stagnant nasty water!
