Hey Stacey,
I, too, have had people say similar things re my boys, "They think these are 'insert derogatory comment here' fish", and I have been concerned at those comments too, however let me share some of my thoughts as to how I dealt with it, in the hope of helping.
It really is unfortunate, but I hate to say it, there will always be people who say these things, and not just about our fish, but also our dogs, cats, hamsters....whatever we keep. But you know what, it really doesn't matter, because our pets, will always be seen differently in our eyes. I found that it's just that they can't see them the way we do. I have also found that most people that I know (not all) change their minds when they take the time to see their personalities, and how they interact with each other, and with us. There's nothing like the way they dance, and beg, and eat, and play that endears us so completely to them (I see them as family members). With that in mind, could I be so bold as to suggest that perhaps a more appropriate way to look at it is to ask whether their subjective approach should be affecting you so much?
I only say that because I used to seek the interest of family and friends in the same way, only to be disappointed when they didn't see it the same way, but I see it differently now. I'm really not too concerned about it these days, but only because I can't see the sense in letting comments like that in any way affect the joy and happiness that I get from my boys. It now makes zero difference to me whether someone else perceives my boys as smart, stupid, ridiculous, a waste of time etc, because to me, they are everything but that, and that's ALL that matters. Remember, it really is only their opinion
PS, delboy makes a great point re the youtube vids, but just bear in mind, that despite watching them, your family may still not see it the way you do...
....anyway, it's just food for thought, but I really hope that you never let the opinions of others affect your experience, joy and happiness with these awesome friends!
