PF - identification point taken...of course FHM and GSH differences are apparent to YOU...and other seasoned pond owners [now to me...little more learning every day] but to a new pond owner and someone learning forage behavior they certainly both have dark upper halves and are shaped similarly which can lead to confusion, at least, if you know what I mean. Of course once one views the entire body the brilliant silver and mouth of the GSH give it away. I've also noticed they move faster and react immediately to any event [like a footstep or shadow] than a FHM. They just seem far more aware of their surroundings while FHM aimlessly float along like they are just leaving a bar in Amsterdam. I guess the impetus for my statement is that I'm holding out hope for the Anderson's/SK relationship here that perhaps SK IS indeed seeing GSH in the shallows along with FHM...?
