Goldfish require an ample supply of vitamins and minerals in their diets. Leafy greens such as lettuce and spinach make an excellent addition. Just be sure to boil or blanch these vegetables beforehand so they remain soft enough for your goldfish to nibble at.
Oranges provide goldfish with much-needed Vitamin C. Strawberries and sweet potatoes also contain essential nutrients.

Pellets
While both flakes and pellets are appropriate options for feeding small Goldfish, higher-grade pellets tend to better retain nutrients while being easier to monitor their consumption. Plus, this form of food makes keeping track of feeding quantities much simpler!
Feed your Goldfish two or three times each day, providing just enough food that they can consume within two minutes. Sinking pellets are another good choice as they allow your Goldfish to consume their meals while feeding beneath the surface without accidentally inhaling air while feeding at the surface.
Fancy Goldfish often require a special floating pellet designed to enhance color. Hikari Blood Red Parrot+ is an excellent choice, boasting natural coloring-enhancing ingredients such as krill, spirulina, astaxanthin marigold flowers chili pepper phaffia yeast and other color boosters that boost pigment. Koi and Goldfish alike will love this food; soak pellets or flakes before offering to your Goldfish to eliminate excess air and soften them before feeding to them!
Frozen Food
Goldfish require a diet high in proteins, vitamins, minerals and trace nutrients. Therefore, it is essential that their fish food has been specifically designed and manufactured for aquarium use – this may take the form of flake food pellets sticks granules tablets etc. Feed a small amount twice or three times each day.
Before feeding them to their fish tank, flakes and pellets of this type should be pre-soaked in water to reduce air pockets and ensure optimal digestion by the fish. This step is especially crucial for feeding fancy goldfish (oranda, black moor, ryukin) with rounder heads since their bodies can more easily become constipated when fed foods that do not dissolve completely in tank water.
Fancy goldfish fishes love to chase and consume live snacks like daphnia or brine shrimp which can be purchased frozen from most pet stores or the pond department. These types of foods contain plenty of protein which help increase metabolisms for reproduction.
Fresh Vegetables
Goldfish are known to feed on various vegetables as an excellent source of nutrition. Vegetables contain high concentrations of fiber which helps digestion. Furthermore, vegetables contain vitamin C which supports immunity as well as important organ functions.
Some of the best vegetables to feed goldfish include zucchini, cabbage and cauliflower. These high-nutrition veggies are easy to digest and should be fed raw or cooked as part of their regular diet – just ensure you clean them beforehand to protect your fish.
Carrots are another highly nutritious vegetable, packed with vitamin C. However, you should only feed them as occasional treats to avoid digestive issues like bloat. Make sure the carrots are peeled and cut into small pieces before offering to your fish. Oranges contain high levels of vitamins and fiber – plus are easy for goldfish to chew through without causing digestive issues!
Gel Food
Some pet stores sell gel foods made specifically for goldfish that combine inverts, vegetables and kelp to provide a nutritionally balanced diet for this species of fish. Not only are these cheaper than store-bought flakes or pellets but they may even help relieve swim bladder issues caused by conventional food sources.
Foods such as this are easy to measure out accurately, and can be given to your fish at a consistent time each day to help establish a feeding schedule and prevent overfeeding which is one of the leading causes of goldfish deaths in captivity.
Make these foods yourself, but be sure to follow a recipe tailored specifically for goldfish and other tropical fish. Blanching or lightly boiling any veggies used in these treats will make them easier for them to digest.
