Does anyone have experience with and suggestions for free feeding strategies? That is, providing ways for a turtle to eat at its own convenience rather than depending on regular feeding from a caretaker.
I used to have loose lettuce leaves floating in her tank, and that seemed somewhat effective. She would nibble at them throughout the day, not over-eating, and I could tell that she took a lot of solace in having control over her nutritional needs. But that also led to a lot of shredded lettuce debris floating around her tank, though I could never tell if it was lettuce shredded by the filter or the remains after passing through the turtle's system.
Has anyone else found effective means of free feeding? Are there things you've tried but that didn't work too well?
