dead fish swimming

Bobl bobl bobl....the eternal sound from the fishtank, where the latest victim took its last swim.
The fish tank is to be compaired to humans deathrow or old peoples rest home...it is their last mortal home before the eternal rest. It is the point of no return whether it is fish or man. If listening very carefully to the bobl bobl bobl in the fish tank you could almost hear the other fish humming "dead fish swimming, dead fish swimming" just seconds before the watertank vacumecleaner sucked it up.
