There are a huge number of goldfish, and some varieties are cheap, so many people will buy them to keep and play, and at the same time buy a pack of food for small goldfish. In fact, goldfish can eat a lot of food, and it is not difficult to raise it well.

They really like to eat a lot. Animals include: planktonic fleas, water worms, dragonflies, cooked egg yolks, earthworms, worms of appropriate size, etc. Plants include: yellow algae, diatom, green algae, radish, duckweed, aquatic plants, bran, bean cake, noodles, rice, bread, etc. In addition, there are all kinds of dry food-dried red worms and artificial feed to choose from. Your goldfish must not taste so good, right? It doesn't matter. Goldfish are not very picky about food. It's okay to eat the same food all your life. As long as it lives, it eats with relish.

Live food is rich in nutrition and has the best palatability. But they usually only grow in dirty ponds, ditches and puddles. They are captured from these natural waters and carry a lot of bacteria and parasites. General cleaning is not easy to clean. Goldfish eat this food for a long time, and it is inevitable that they will get sick. Common diseases are white spot disease, gill rot disease and third-generation worm disease, and these three diseases are the most difficult to cure. If found in time, it can be cured after treatment. But the pathogen enters the fish tank with each feeding, and it won't be long before goldfish will get the same disease.
