"But all three were created between 1893-1908 "
By reading this below, I get the impression that they are not that old :
"the variety, and characteristics, of goldfish available in aquarium stores have changed dramatically during the past 20 years.
Most beginners are not really interested in the ordinary goldfish of yesterday - what today's market appallingly labels as "feeder goldfish."
Instead, goldfish keepers are attracted to the growing number of "fancy" goldfish varieties: lionheads veiltails, moors, bubble eyes, celestials, etc."

By reading this below, I get the impression that they are not that old : "the variety, and characteristics, of goldfish available in aquarium stores have changed dramatically during the past 20 years.

Well there is last time I checked 144 different breeds of goldfish, The reason why the fancy breeds are popular now a days as opposed to the past is because of technology, i.e. better filters, heaters, etc. which makes raising them and transporting them much more easy so they are relatively cheap. When Goldfish first came to America in 1800's one fish could cost $100s to $1000s of dollars in today's money. And I am sure today's bubbleeye for example is different from the original in 1903

But I don't understand the point of your question, What difference does it make if they were evolved yesterday or 100 years ago, They still evolved.

But if I use the bubble eye we can even trace it's evolutionary transistional forms from the

Common goldfish ~1000 AD

to the Telescope (Globe eye) in 1592

to the Celestal in 1870

To the Bubble eye in 1903
