Ever found yourself gazing at your beloved goldfish, enjoying their peaceful swimming, only to realize with a sudden jolt that you’re completely out of their regular fish food? Panic might start to set in! While it’s true that goldfish can survive without food for up to two weeks, letting them go hungry for too long isn’t good for their health.
The good news is, you probably have plenty of nutritious alternatives right in your kitchen! Goldfish are natural omnivores, meaning they enjoy a varied diet of fruits, vegetables, proteins, and even some plants. So, when the pet store run isn’t an option right away, you can offer your finned friends some human-grade snacks to tide them over.

Safe & Yummy Alternatives from Your Kitchen
Here are some surprising yet healthy foods you can feed your goldfish until you restock their usual pellets or flakes:
Fruity Delights
Fruits offer a natural sweetness along with essential vitamins, minerals, and fiber. Just remember to prepare them properly!
- Oranges: A great source of Vitamin C, vital for healthy goldfish. Peel the orange, remove any stringy pulp, and cut the flesh into tiny, bite-sized pieces. Due to their acidity, offer oranges only occasionally to avoid affecting your tank’s pH balance.
- Strawberries: Both fresh and thawed frozen strawberries make a tasty treat. They’re rich in fiber, carbohydrates, manganese, and polyphenols. Always cut them into very small pieces before feeding.
- Raspberries: High in Vitamin K, raspberries contribute to strong bones and healthy blood. Separate them into individual drupelets and feed just a few at a time, as they can sometimes make the water a bit cloudy.
- Grapes: A healthy substitute! Wash grapes thoroughly, peel off the skin, and dice the flesh into tiny, manageable bits. Grapes are packed with carbohydrates, fiber, and potassium, all beneficial for your goldfish’s health. One or two small pieces are usually enough for an adult fish.
Veggie Powerhouses
Vegetables provide goldfish with important vitamins, minerals, and plant-based nutrients.
- Leafy Greens (Spinach, Kale, Romaine Lettuce): Excellent sources of carotenoids, Vitamin K, and folate. Remove any thick stems and blanch (briefly boil) or steam the leaves to soften them before dicing into tiny pieces. Darker greens like baby spinach are often more nutritious.
- Zucchini: Wash, peel, and slice zucchini into thin, quarter-inch pieces. You can blanch or microwave it slightly to soften it up. Zucchini offers Vitamin A, potassium, and folate.
- Cucumber: Chop cucumbers into small cubes. They provide Vitamin C, potassium, and beta-carotene. Since they’re mostly water, they won’t dirty your tank much.
- Peas: A fantastic source of fiber for digestion! Thaw frozen peas and gently pop them out of their skins before feeding. Peas sink, making them easy for goldfish to find and eat.
- Sweet Potato: An inexpensive superfood rich in carbohydrates, fiber, and protein. Wash and skin the potato, then chop it into small pieces. Baking, steaming, or microwaving the flesh can make it easier for your fish to digest.
Protein Boosters (in moderation!)
While goldfish don’t need as much protein as carnivorous fish, small amounts are good for their growth and overall health.
- Shrimp: Thawed frozen or freeze-dried shrimp (like brine shrimp or daphnia) make protein-rich treats. Remember to remove the shells first.
- Mealworms: If you’re feeling adventurous, purchase live mealworms from a reputable pet store. Goldfish often enjoy chasing and eating these. Avoid mealworms sold for birds, as they might contain additives.
- Hard-Boiled Egg Yolk: Offer just the yolk, as the white is less digestible for fish. While eggs can help young fish grow, adult goldfish need foods lower in protein. A key drawback is that egg yolk can quickly cloud the tank water, so feed sparingly and remove any uneaten pieces promptly to maintain water quality.
- Worms: Pet stores often sell safe, nutritious options like bloodworms, tubifex, and small earthworms. Dice larger worms to prevent choking hazards. Never feed worms found in your garden, as they might carry parasites or pesticides.
DIY Gel Food
Feeling crafty? Making your own gel food is a nutritious and economical option! Blend goldfish-safe ingredients like shrimp, spinach, and a touch of garlic, then mix with gelatin. Pour into a pan to set, then cut into small cubes. This allows for customized nutrition based on what you have.
Aquatic Plant Snacks
Live aquatic plants aren’t just pretty; they also offer a natural, edible snack source for your goldfish!
- Duckweed
- Azolla
- Anacharis
- Salvinia
Always research any plant before adding it to your tank to ensure it’s safe for consumption and hasn’t been treated with chemicals or pesticides.
Important! Foods to AVOID
While goldfish aren’t usually picky, some human foods are strictly off-limits and can be harmful:
- Chocolate
- Carbonated beverages
- Chips
- Pasta
- Bread and crackers
- Fatty meats
- Sugary treats
- Any food with artificial colors, preservatives, excessive salt, or other additives.
- Even natural foods like corn, soy, rice, and wheat are not good choices for goldfish.
The Best Diet: Variety is Key!
Remember, the foods listed above are meant to be occasional treats or temporary solutions when you’re out of regular goldfish food. For optimal nutrition and long-term health, your goldfish thrive on a balanced diet of high-quality goldfish pellets or flakes daily. Supplementing this with freeze-dried bloodworms, brine shrimp, and veggie clips can add beneficial variety.
A diverse diet ensures your fish gets all the protein, carbohydrates, vitamins, and minerals they need to live a happy, healthy life. Always follow the feeding guidelines on your fish food package to avoid overfeeding, which can lead to health and water quality issues.
Going on Vacation?
Leaving your goldfish for a few days doesn’t have to mean they go hungry. Here are some options:
- Pet Sitter: Have a trusted friend or professional pet sitter feed your fish daily.
- Automatic Fish Feeder: Invest in a reliable automatic feeder that dispenses food at set times.
- Vacation Blocks: Use time-release vacation blocks that slowly dissolve, providing food over several days or weeks.
Before any trip, perform a water change and tank cleaning to ensure your goldfish have the best environment. Avoid the temptation to overfeed right before you leave!
Running out of fish food can be stressful, but it doesn’t have to be a crisis. With a little creativity and knowledge of what can goldfish eat other than fish food, you can provide healthy, nutritious alternatives from your own home. Just be sure to restock their specialized food as soon as possible for their continued well-being!
