you really are not alone,
i left a tank draining one time,sure the hose wouldn't fall out of the tank............
yeah right,it did,it got so low my angel fish was flapping on the gravel,he damaged
himself badly and i lost him some time after,not to mention a soggy carpet.that was a
juwel 96.......the tank of doom if anyone remembers.
another time i came back from holiday and my filter had burnt out,most of the fish had died,
the gravel was a heaving squelch of all things dead,and that one made me cry,coz i lost
my clown loaches to that one,and that was the big filter for the 4ft tank.
oh and i found a dead frog whilst moving the furniture ready for decorating,i lost him some time back,
so he was a virtual fossil

just thought i'd try and make you feel a little better lol
