no, i like fish but i prefer to raise a dog. its more fun and fish are quiet. you dont even know why the heck the living...

Maybe that's the whole idea. Having a quite and less attention seeking and expensive pet. Dogs are not for everyone. They are lovly but need lots of care and attention. Not great for someone who lives a busy life. Fish only the other hand need less space, less care, less money and less noisy. Yeah you can't give them a hug (Can pet them if you have right type of fish) but they makes their owners happy too.
