What does the F1 or F2 mean??

[Biggfeast]

i see it alot where the speices name will be written and then there will be a F1 or F2 sometimes, i was jus curious as to what this means??? ne help?

 

[amv123]

i was wondering the same thing, ive also seen F0...

 

[stevenrox]

F0 is wild caught F1 is breed in tank (with sibling?) etc

f0 is wild caught, f1 is the wild caught's off spring and f2 is the off spring of the off spring of the wild caught.

OOOOh okay, yeh i see it all the time for people tryna seel fish, that makes sense tho, thanks for the info

It's the generation from the wild. F0 is wild caught, F1 is from wild caught parents (1 generation from wild), F2 is from F1 parents (2 generations from wild), etc.

just to be an ass what is a fish from a F0 and F2 parents?

 

[flowerpower]

Just a thought. W/ all the concern over F#, shouldn't there be a way to distinguish between F2 fish that are inbred vs those that aren't? or is it just assumed that most F2's are inbred?

 

[Biggfeast]

okay, so new question, does these F#'s make a difference, like color? size? hardiness?? ne of that

That's debatable. Some might say closer to F0 fish have better coloration or whatever but I think the main thing is knowing that your fish is pure bred. For some species this doesn't really matter. However, fish such as red devils and midas cichlids are so interbred that the only surefire way to know your fish is a purebred is if it is F0. There's a similar situation with trimacs which are more often flowerhorns than actual trimacs.
