I'm not sure if I'm under feeding my turtles when it comes to lettuce. I know for pellets you're supposed to give them the amount of their head, but I'm not sure how much to give them when I feed them lettuce.
I give them 4-5 small pieces each (they're 5 inches long). One seems fine with that amount, but the other becomes a food bum by the evening. I'm paranoid of over feeding them, so I don't give into the bumming.
I've looked around the forum and haven't found much in regards to the amount. 1 person on this forum had said to give them as much as they want, but I think that would be too much. :/
