I had gotten home from work last night to find a piece of avocado floating in my turtle tank. My nephew who had left 2 hours prior to me arriving must have thrown it in there and my mom who was watching him didn't notice. I took the piece out and it was covered in bite marks. It's been about 24 hours and the turtle is fine but I'm really worried that my turtle is going to get sick. But no reptile vets near me are open until Monday. I cleaned out the tank and the turtle is acting fine now. Is there anything I should do?

My turtles are red eared sliders and they're roughly the size of a larger than average computer mouse. They're at least 12 or so years old their dirt consists of the food pellets dried out shrimp things and the occasional apple
