Ok, since it seems we've thrown the whole kitchen sink in here I'll chip in my two cents.
Ok, enough idioms.
But really, here I go:
To me, while I would never mistreat my fish or neglect them, I do not treat them as a pet. They may seem to act like they are "begging for food," or "following your finger," but I really just think it is them acting on instinct.
But I'm not an animal psychologist, so I very well might be wrong. In fact, that's the thing about arguments. We could be 976,564.3% sure we are right one minute and then be presented with one fact and realize how undeniably wrong we were the next. Just remember that folks.
So anyway, I don't claim to be correct at all, this is just what I think.
I personally treat my tank as "living art." I create it, I change it, etc. I don't name my fish I don't play with them or pretend that they have any intimate knowledge of their surroundings. They are not pets (to ME!!! Maybe to you they are but that's your opinion and this is mine so I don't CARE), they are an element of a piece of artwork, a figure in the foreground of a painting, and not much more.
