Hi bunjiweb
I wouldn't go so far as to say I hate guppies, but I'm not happy with most of them I see at the lfs these days.
When I was a kid, guppies had not been overly inbred like they are now. They were always perky and pretty little fish and each one was different from the next.
True, they were not as fancy and their overall size and the length of their tails was not what it is now, but it was exciting to watch fry grow and develop their individual colors and patterns. Each one was unique and special.
These days, they are lucky they can swim at all with their over-sized fins and tail. They are prone to illness more easily too, it seems to me. When humans breed for special qualities in a fish, IMHO, for everything they gain in beauty, they lose something in stamina.
I think it's a sad thing to see fish bred that way since it does not benefit them in any way. They are only selectively bred to please the fickle whims of humans.
Of course, it's not the fishes fault. I like them for what they are, but I'm not overly fond of the people who make them that way.
