Your turtle is looking for "cover"
You would do well to add some floating plants.
If the turtle feels exposed it will stress it out.
Because turtles have slow metabolism, ifit becomes ill, it will not show any sign of illness for at least 6 months. Also if this is a RES and less than a year old, feed live food. If older they are primarily plant eaters but will nosh on an opportunity.
HTH. I kept turtles for somewhere around 30 years
