Dennis it looks like we're going to need a layout of your home.
Your complete schedule including feeding times for Wally?
when the lights go on and off in your tank?
are you directly below a flight path near a major metropolitan airport?
do you think the fish could be unhappy with the Dallas Cowboys current record?
Is there a possibility that you've blinded the fish with the flash from your camera?
Is it possible that he's embarassed by the car you drive?
Maybe he likes a rectangular tank?
Could he be upset with that little bare spot that you have in the corner of your tank?
Have you made any derogatory comments about his fins or the way he swims?
Have you filed a complete tax return?
We're gonna get to the bottom of this.
