Water cows and pigs

I consider myself unfortunate.  I have witnessed the beauty of gold fish. Especially the Oranda  and the black moore.
 I would really like to have a couple to look at while I have my breakfast.
Unfortunately I don't have space for such big fish. They are real cows of the fish world. I mean all the poop they produce... Well, even the looks are somewhat cowish (the huge belly).
OK, there are goldfish that would probably either make me very sad or make laugh every time I see them. Look at this and this. O h,  m y  g o d !
