I disagree with your feeding schedule.
You are giving way too much protein. Your turtles might be fine now, but they will develop pyramiding and gain weight as they get older.
Raw shrimp are much too high in protein to be giving even once a month. Most people only give them to their turtles a couple times a year.
Goldfish have no place being in a turtle tank. They are useless as a feeder fish for turtles. They have a very high fatty content and low nutritional value.
http://www.redearslider.com/index_nutrition.html I suggest you read over that section again and re-evaluate your turtles diets.
Raising turtles is not rocket science, But it takes a lot of knowledge and dedication to properly care for them.
