Goldfish are omnivorous animals. They can eat various types of food, including fish worms, dried fish food, frozen worms, and some special goldfish feed. However, if you keep goldfish at home and don't have special feed, don't worry. There are many common household foods that can be fed to them.
Rice: Cooked rice is a good choice for goldfish. However, note that before feeding, make sure the rice has cooled down and don't feed too much, because rice is easy to decompose in water and pollute the water quality.
Breadcrumbs: Similar to rice, breadcrumbs can also be fed to goldfish as emergency food. But again, don't feed too much to avoid deteriorating water quality.
Cooked vegetables: Some cooked vegetables such as peas, carrots, or spinach can also be used as food for goldfish. Before feeding, make sure the vegetables have cooled down and are cut into appropriate-sized pieces.
Egg yolk: Cooked egg yolk is also a favorite food of goldfish. Crush the cooked egg yolk and then feed it to goldfish. However, note that don't feed too much because the fat content in egg yolk is very high.
