What do goldfish eat

1. Generally, fisheries are collected on the spot, similar to bean cake, rice bran, pasta, and shrimp powder can all be used as feed.

2. Nowadays, aquarists often use artificial feed or natural bait. Artificial bait sold on the market is generally nutritionally balanced, and the packaging indicates the proportion of nutrients such as protein, fat, and fiber, which is more economical for aquarists. heart.

3. The natural bait for goldfish is red worms, blood worms, water earthworms, bread worms, fish and shrimp meat, among which red worms and blood worms are very nutritious.

4. Breadworms are relatively common and are often used for feeding birds. They can be bought in the general bird and flower markets, and they are artificially fed. They are relatively clean, and the protein content is high, which is a suitable bait in natural bait. Precautions:

1. Red worms and blood worms are very nutritious, but due to the influence of their growing environment, such as rinsing is not easy to bring in bacteria and worms, which can make the fish sick.

2. The selection of artificial feed is reasonable, and many inferior fish foods can easily lead to indigestion of goldfish and die. How to feed goldfish

Goldfish are difficult to raise in summer, with high temperatures and many diseases. The yellow mold is the hardest to raise in the season and the best to raise in the winter. The key is to master feeding, light, water quality, and density. Tips for raising goldfish:

1. Feeding: Feeding should be fed with nutritious animal feed and white sesame. Animal feeds such as daphnia, earthworms, mealworms, green worms, skin worms, etc. Earthworms and sesame are mainly fed. Both red and black earthworms can be fed. Do not feed inferior goldfish feed that you buy. Because this kind of feed has too much starch, its nutrition is poor, it is not easy to digest, and its water quality is easy to be polluted. If the goldfish eats malnutrition, the growth of goldfish is slower and it is more likely to get sick.

2. Illumination: It is best to place the fish tank in a place where there is sunlight for 1-2 hours. In this way, the ultraviolet rays of sunlight are used for sterilization. Play a role in preventing disease. This can reduce disease. As far as possible, the prevention of fish disease is mainly supplemented by medication. At the same time, due to photosynthesis, the color of the fish body is also bright and beautiful.

3. Change the water: Change the water frequently to increase the dissolved oxygen in the water. When changing water, only one-third to one-fourth can be changed. You can't change a lot at one time. It is important to keep the water in the aquarium clear. There is sufficient dissolved oxygen in the water for the fish to grow and grow fast. Otherwise it will stop growing and even die.

4. Stocking density: Domestic rectangular aquariums should not be raised due to their small size. For example, in a container with a length of 40 cm, a width of 25 cm, and a height of 30 cm, 6 to 8 small goldfish with a length of 5 to 7 cm can be raised. For example, a round glass tank with a diameter of 26 cm and a height of 13 cm can raise 4 to 6 cm of small goldfish. Adult fish with a body longer than 8 cm are not suitable for rearing in small glass tanks, but need to be reared in luxurious large glass tanks or ceramic tanks, and equipped with a small oxygenator to prevent hypoxia. These stocking densities are for reference only, but also depend on the water temperature, the strength of the fish, and the quality of the water. They cannot be mechanical. Generally speaking, the fish is large and the number of fish is small; the fish is raised in winter and the fish in summer; the fish can be raised when the water temperature is low and the fish are raised when the water temperature is high.
