, What exactly does F1 mean? What makes an F1 an F1?
F0 is a wild caught fish...
F1 is the tank bred offspring of two wild caught fish...
F2 is the tank bred offspring of two F1 fish...
etc...
F1 is the tank bred offspring of two wild caught fish...
F2 is the tank bred offspring of two F1 fish...
etc...

well said, but beware! Ive caught a few keepers calling their f1s wild, and there is no way of telling the difference

Yup, and there is also some differing opinions of what the offspring of an F0 x F2 pair would be... some say F1, some say F3...
In the end, when making a purchase, I suggest we all ask for specific descriptions of what we are buying and not rely on short hand. I mean... is it really that hard to type out 'wild caught'? lol
And there will always be those eager to lie to make a buck. I talked to someone not long ago who was about to pay $100 for a 1" "Wild Caught Blue Dempsey"... (for those unfamilar, there has never been a Blue Dempsey seen/caught in the wild).
I personally would never pay extra for an F# fish unless I trusted the seller or personally (not internet) know someone reliable who will vouche for them.
Yeah everything said is true. But the problem is, you may never know what you got. Theres no way to tell if the fish are truely wild caught or F1 etc. Like NC_Nutcase said, you gotta buy from a reliable source and ask around about the person if you could etc.
But technically the term F1 is used when hybridising fish. Its the first generation of young from them i believe
Actually...
When scientists are doing an experiment on breeding... The first batch of offspring are F1... the second are F2... etc...
It doesn't matter if the originals are wild caught, hybrids or a pure aquarium strain.
Then we borrowed their labeling system to describe how far our fish are from wild caught and create the infamous "F0" label for our wilds. This numbering system was not created to deal with crossing generations, such as breeding F1 x F4. In a science experiment when crossing two different generations (which would be rare/odd) there would be a full description of what they bred and why...
At least that's the story I've always heard... there are articles out there that explain it this way as well.
Edit/PS - Bruce is probably right also, as hybrid creators could also borrow this same labeling system to track their hybrids. I didn't mean to sound like I was trying to "correct" anyone.
