Answer
Hello Jari, I don't think there is anything wrong with your turtles. It is very normal for turtles and other reptiles to not eat when they have been moved to a new environment. It can sometimes take a week or more before they will start eating. My aquatic turtle behaved the same way when I acquired her.  
Young turtles like yours will feel more safe and secure if you have some plants in the water that they can hide in. They would normally spend their time hiding among aquatic plants in the wild and probably feel very nervous in such an open, exposed area. You can use real or plastic plants for this purpose. They will become more tame in time and will not need the plants as much. Your food is fine, I use the same kind. Turtles also respond well to live food. You might want to try some worms like earthworms or mealworms or some small fish.
