Welcome!
Your vet is correct about the feeder fish- guppies or rosy red minnows are MUCH healthier than goldfish. Goldfish are too fatty. But, either way, feeder fish should only be a rare treat since they're high in protein. If you turtle is still getting used to a larger set up, it may take him a little while to grow accustomed to hunting fish- but he'll get the hang of it.
As you have an adult RES, he's not growing very quickly at all anymore. So, his diet should be adjusted to fit his needs. You should be feeding him vegetables daily and one "headful" of pellets every other day. Leafy greens are excellent veggies to feed- take a look at the nutrition tabs to see "what to feed" and "what not to feed."
Lighting is also important for nutrition. Make sure your turtle has a UVB light to help him produce vitamin D3. Make sure he also has a UVA (heat) bulb to entice him out to bask so he can warm up to properly digest food.
