The only difference I would say, would be colouration, but then again, there are so many different geographical "varients" of agassizi you would be hard pushed to see a tank bred one which originates from same area. I tend to assume that most fish in lfs are captive bred, regardless of how they are labelled, the closest to wild I've kept myself are F1's and I know they are, because I know where the parents came from.

guy i got them off is also selling f1s may be just calling wild to get extra money ,what does lfs stand for
thanks

Perhaps, unless they are the parents of the F1's hes selling?? Dont know. A lot of people do use Wild Caught a lot to bump up the prices so you got to be careful and know where these fish are coming from.
