Oops. Yeah, that'd do it. At least your fish isn't like my apparently ******ed wall-clinger one who got himself stuck to the countertop while I was cleaning his tank.
While rushing to clean Happy's tank, I quickly scooped him out with the fish net thing before putting him into a bowl I thought I put water in. I started walking away to find the water conditioner, heard a flopping noise, and looked back to see that my fish had no water.
