Feeding methods of grass goldfish

1. Density: the feeding density of grass goldfish should be less, not more. Usually, adult fish with a length of more than 8 cm should not be raised in a small glass tank, but should be raised in a large glass tank or in a ceramic tank and equipped with a small aerator to prevent hypoxia.

2. Feeding: grass goldfish is fed with nutritious animal feed (water fleas, earthworms) and white sesame, etc., do not feed inferior grass goldfish feed bought, usually in the morning and afternoon, should not be fed more, in order to eat up.

3. Lighting: when raising grass goldfish, it is best to put the fish tank where the sun is exposed for 1 to 2 hours, so that the ultraviolet rays of sunlight can be used to sterilize and prevent the disease. at the same time, due to photosynthesis, the color of the fish is also more bright and beautiful.

4. Water change: grass goldfish can increase the dissolved oxygen in the water by changing water frequently. When changing water, only 1/3 to 1/4 can be changed, and many of them will not adapt at once. There is no final conclusion when to change the water. Depending on the water quality, the water quality is often changed when the water is muddy.

Four Seasons Management of Grass goldfish

1. Spring: spring is the breeding season for goldfish, the breeding work is mainly focused on parent fish spawning and larval care, parent fish should be fed live bait as far as possible during the breeding period. Plum rain season is the onset season of goldfish. Goldfish with disease should be isolated in time and prevented with drugs in advance.

2. Summer: the water temperature in summer is more than 25 degrees Celsius, and the harmful bacteria and parasites in the water are obviously reduced, so they rarely get sick. However, due to the high water temperature, the algae in the water increased significantly, and the amount of dissolved oxygen in the water decreased. At this time, the focus of feeding work is to prevent heatstroke and hypoxia.

3. Autumn: the young fish produced in spring have reached the adult stage in autumn, so we should focus on feeding and keeping the fat shape of ornamental fish, so fattening work is the focus of feeding in autumn. At the same time, autumn is also the season with more diseases, so active prevention should be taken.

4. Winter: although it is difficult to increase the body length of fish in winter, the degree of obesity of fish can increase, and ornamental fish have developed. This is the busiest season for the purchase and sale of ornamental fish. The focus of this is to maintain the stability of water quality and the health of ornamental fish.

4. Red dot disease

[symptoms] there are obvious red spots on the side of the body and abdomen.

[prevention and treatment] the tank water can be changed immediately and can be cured without medicine, while seriously diseased fish need to be isolated and treated with antibiotics.
