Do redears actually NEED things with shells or will/can they thrive on a fish diet alone? I see snails and other hard backed thingies as something that redears can help control but not really need as part of their daily bread. Give me some help here.
I think RES do just fine without mollusks as long as other slow-moving and bottom-dwelling forage is plentiful. If their preferred mollusks and insect larvae are scarce, the downward gazing eyes of the RES may put them at a disadvantage. That's just an educated guess.
