Goldfish are omnivorous animals. In the absence of special fish feed, the following foods can be used as temporary substitutes for feeding:
Plant-based Foods
Vegetables: Such as spinach, lettuce, carrots, etc. They are rich in vitamins and minerals. These vegetables should be chopped or cooked before being fed to the goldfish.
Fruits: Such as apples, bananas, etc. Peel and remove the cores, then cut them into small pieces. Feed them occasionally, but control the amount to avoid excessive sugar intake.
Aquatic Plants: Such as duckweed, water celery, softstem bulrush, etc. These can be directly placed in the fish tank for the goldfish to eat.
Grains and Pastries
Cooked Rice: Knead it into small grains and feed it, but in small amounts to avoid polluting the water quality.
Bread Crumbs: Choose sugar-free and oil-free bread crumbs as a temporary food, but control the feeding amount.
Protein Sources
Egg Yolk: Cook it and then crush it before feeding. It is rich in protein, but should be fed in small amounts to prevent water pollution.
Live or Frozen Baits: Such as water fleas, brine shrimp, bloodworms, etc. They are rich in protein, but pay attention to disinfection.
Other Substitutes
Grains like millet, wheat grains, and corn kernels should be cooked before being fed.
Shrimp meat, lean meat, etc. Chop them up and feed in small amounts.
Precautions:
When feeding, follow the principle of "feeding small amounts multiple times" to avoid indigestion or water quality deterioration caused by overfeeding.
When trying new foods for the first time, observe the goldfish's reaction to ensure that it can adapt.
For long-term feeding, special fish feed should still be the main food source to ensure a balanced nutrition.
Through the above methods, the basic nutritional needs of goldfish can be met in the absence of fish feed.
