Not all Grass Carp hit the news

[4got10]

Ok so I was wrong with that last comment but I disagree with a few things:

The first goldfish were bred from Prussian carps. It started with basic mutations such as the colour. Seeing as they were rare, those fish were kept safe and further selectively bred to bear features that we have today (split tails, telescopic eyes, longer tails, etc). I was wrong with which types of goldfish came from which carp. To clarify, goldfish were bred from Prussian carps and koi bred from common carps (difference lies in the barbel; koi retained theirs from common carp). This would be why if you left the goldfish to breed as they please without being culled, they'd go back to what they were before being domesticated, Prussian carp which isn't what the thread originally was about, oops!

Yes, goldfish are their own species but I don't necessarily agree with that either. They were bred based on recessive mutations to bring out something that was more aesthetically appealing, but its just that; mutations. We wouldn't call someone with a progeria mutation not human and give them a label, or label someone with blue eyes as a different kind of human.

Furthermore, I think that the four types of carp grouped as "Asian" is only done because of where they came from geographically, not based on their threat level or behaviour.

My facts were wrong and this post made me do some research to correct that information.

What I learned: nah, tossing the goldfish into a lake wasn't the cause of this carp problem. Just threw a theory out there but I guess, MYTH BUSTED!
