If you run out of fish food, there are several alternative foods you can feed your goldfish temporarily. Here are some of the most common things you might have in your fridge, freezer, or cabinets:
- Green, leafy vegetables (lettuce, kale, spinach)
- Peas
- Sweet potato
- Zucchini
- Cucumber
- Raspberries
- Oranges
- Strawberries
- Brine shrimp
- Spinach
- Garlic seasoning
- Gelatin
- Hard-boiled egg
- Grapes
Keep in mind that your goldfish needs a very balanced diet, so these selections should be used in emergencies or for snacks only. Also, avoid feeding cheese, rice, bread, crackers, and high-fat foods to your goldfish, as they are not suitable for them. Finally, remember that goldfish can survive without food for up to 15 days, but it is not recommended to starve them for that long.
