Vote for Fishes

Arguments for fishes (from one piscean to another)
You dont have to take them for a walk. Their constant motion ensures that they get enough excercise
You dont have to pick up their poo..I mean you cant even see the poo
No cleaning of teeth, no bath, no removing ticks.
You dont have to pay them any attention if you dont want to. Even when you gaze at them unblinkingly they ignore you.
They dont lick or bite. Infact there is no equivalent of a bark emanating from them
You can have more of them and still not feel a dent in the pocket.
If you lose one of them you dont feel so emotionally stirred as when you lose a dog...i.e. not unless you start christening them teddy etc.
Anybody who reads this can add to the list
