You got that right ewest.

For me anything under a couple inches is very hard. Over two inches and the GSF shape and mouth size and green cheek bars start making them easier to tell. With RES they have to get up to about 3" before it starts become evident for me. At least evident enough I would feel safe stocking them in a specific pond for a specific species.

Add in hybridization and it gets even more tricky.

Even at those sizes I would probably get some wrong. smirk

Throw in a species I'm not expecting to see in the pond (like Rock Bass, crappie, etc.) and then all bets are off.

Edit: Adding a link here to a thread about feeding GSF so I can find it later. What to feed GSF
