Thanks ewest.

Dave, I compared my fish to the GSF description that ewest posted and there is no conflicting indicators. The description gives a lot of room for variation of colors, and when I count spines and rays it matches.

I'm sure that there could be other sunfish gene's in this fish, what I wonder is if it matters for my purposes. It's not likely that it has genes for any smaller fish, and it's got the right shape. Can anyone explain to me if it really matters in this experiment that I confirm pure GSF genes?
