If you take a look at the picture there are flowing leaves in the plastic container. I had the turtles wait in there temporary while I cleaned the tank. After i finished cleaning the tank I found out there were many flowing pieces of vegetable like pieces flowing in the water. I did feed them vegetable the day before this picture was taken. I had a whole piece or two of vegetable for my turtles to eat. But looking back at the pictures, it looks like the vegetable didn't even get digested by the turtles.
I fed them baby "bok choy" by the way. They love it more than the lettuce, maybe the baby bok choy have a rich dark green color whereas the lettuce have a slight green color.
