Goldfish are nasty, I dont recomend them But heres a good list:
Feeder Items: live feeder fish (guppies, minnows), earthworms, crickets, waxworms, earthworms, silkworms, aquatic snails, blood worms, daphnia, shrimp, krill, mealworms. For very small turtles, prey may have to be cut into smaller pieces. Larger turtles can be offered larger items like tadpoles.
Leafy greens: collard, mustard and dandelion greens, kale, bok choy. Head (iceberg) lettuce should never be feed as it contains very little nutrition, but dark green leaf lettuces (e.g romaine) can be feed sparingly
Aquatic plants: in an aquarium or pond you can add aquatic plants on which turtles usually love to snack. Submerged plants like anacharis are often eaten, as are water hyacinth, water lettuce, duckweed, azolla (fairy moss), and frog-bit.
Other vegetables: carrots (tops are fine too), squash and green beans.
That should help
