Mike, I am not familiar with the term F0 being a wild caught fish. We, in the UK use w/c or wild caught. Offspring from w/c and F1 parents are F1 / F2. Helen. >Most people use F0 for wild caught fish. F1 fish are offspring from wild caught fish. >F2 fish are offspring from F1 fish, and so on down the line. I've always wondered >what they call offspring from one wild parent and an F1. F1.5? LOL > >Mike Wise ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@majordomo.pobox.com.
