doesn't really work once the wild fish spawn. I'd say 80% prob don't even care until they see the difference and still wouldn't matter.
Cichlid "F System"

Well, as Juan points out....there is nothing regulating this. I will see if I can get some different input from some other folks in the know.

I really like to think of it as number of generations (or level of progeny) from the(an) original, in this case the original is a wild-caught fish. The whole system is still used in plant breeding and really any type of scientific discussion or explanation of the level of progeny. In terms of cichlids, I believe the way it is explained in the first post is best. It really works best if you are back-crossing progeny from an individual back to the original individual. I imagine this would be done to "pure-up" a certain trait of that wild-type (wild-caught) individual. Not much different than how blue dempseys are produced.
As Modest Man said the terms arent being used correctly in the hobby so making further designations for f2+f3=? is just plain silly.Either the fish are wild caught or they are tank raised.And to further split hairs alot of so called wild caught(rift lake fish in particular) are raised lake side in ponds.
So except for the few keepers who catch the fish personally "wild caught" is open to interpretation.Mainly extra $$$ for bragging rights.

I sent the question out to a few guys whose name's you might recognize.

I was asked a question that I wasn't sure of the answer. What is the label put on a fish when an F0 mates with an F2 or an F3? Is it an F1? Something else?
Thanks,
Mo

ive always wondered what the f system was about. but to me an oscar is an oscar, a jag is a jag, a hybrid is a hybrid 
imagine if humans were labelled so. what number would we get?

Thanks for the compliments and additional input. It would be great if this was made a sticky...
You really have me thinking about the human thing, I think we're all "wild" if that is the proper term.
I disagree, there is a noticeable difference between wild caught fish and tank raised fish. Wild labiatus have larger lips, wild managuense larger teeth, not to mention how much more desirable an F0 oscar is compared to a tank raised oscar. These traits are lost after generations in captivity as they are no longer needed. To each his own though.Gaz_ham;1946510; said:ive always wondered what the f system was about. but to me an oscar is an oscar, a jag is a jag, a hybrid is a hybrid

Using your example of averages, you have to remember that the fry would be a generation below each parent.
Parent 1...f1..fry=f2
Parent 2...f2..fry=f3
Fry averaged out would be f2.5. showing lower generation than both parents
but done with
Parent 1..f0...fry=f1
Parent 2..f2...fry=f3 the fry average out to f2 the same as parent 2
Now with
Parent 1..f0...fry=f1
Parent 2..f3...fry=f4 the fry end up f2.5 higher than parent 2 but technically the same strength in gene pool as example 1.
As you can see as the f generation gets further apart it changes the out come somewhat from the fry being lower generation than both parents to the fry being a higher generation than 1 of the parents.
This system could work and technically it is correct but it is more complicated than just calling your offspring a generation lower than the lowest parent.JMO
