I've had my turtles since 1997 and now they are really big (ones about 6-7 inches, other is 8-9 inches) and I've been feeding them too much protein I think. I usually feed them pellets, crickets, small shrimp, and fish. I try to feed them vegetables or fruits but they just don't respond too well. I offer it to them at least weekly since I've had them...
They completely ignore lettuce/romaine-lettuce and hardly touch it. They respond to carrots (I use baby carrots and make them softer by heating it in water) but they don't eat that much of it. I've tried feeding them lots of fruits like strawberries, apples, pears, and even oranges heh - they try it but never eat the entire thing I offer.
So what other vegetable can I try? Their older now and they eat less pellets when I offer it to them so I'm sure they want to eat some herbivor stuff... so does anyone have any suggestions?
Right now I'm kind of "starving" them (as I was told a while back)... after 3 days of not feeding I gave them carrots but they still didn't finish the entire meal. They don't seem that hungry as you'd think they'd be on the 4th day.. I will attempt more carrots later and hope they eat the entire meal.
