Oh, just notice, you dont need to feed him every day past the really small hachling state. In fact if you do that your turtle will grow faster than normal and will become fat (as he already is) wich can have serious metabolic problems later including heart ,liver and kidney problems all of wich are very dificult to treat in turtles and will shorten your turtle´s life. So at most for now give him food every other day(every 2 days would be better). Also you are overusing on to fat, low calcium foods. Cut with the gold fish they are to fat, they can transmit hillness to your turtle and they have tyaminase wich binds with the B vitamins complex and prevents them from being absorved by your turt body. Low fat meat (turkey ,chicken,etc) can be used but ocasionaly (no more than one or 2 times a week). Insted give your turtle stuff like turtle pellets, predatory fish pellets (see also if you can find vegetable based pellets) , fish fillets or wolle small food fish like trout, smellt, minows,etc, feeder fish (dont use cyprinids like rosy reds or gold fish, insted use small tilapia, gupys,convicts,etc all healty and gut loaded), large insects like roaches, crayfish, shrimp,etc. They can also acept vegetable mater wich is very important. You can put in daily a peace of a leafy green and your turt will eat at will
