How about silver carp?
1, goldfish has a wide range of feeding habits, and it is an omnivorous fish that mainly feeds on animals. Food is required to be rich in protein, fat, carbohydrates, vitamins, inorganic salts and trace elements. This is the necessary material basis for the growth and development of goldfish.
2. Goldfish is a kind of temperature-changing animal. Its body temperature can change with the water temperature, but it can't change indefinitely with the water temperature. Too cold or too hot will affect the growth and development of goldfish. The optimum living environment temperature of goldfish is 22 ~ 24℃, which is also called the optimum growth temperature. At the optimum temperature, goldfish seek food extremely vigorously, with the fastest growth rate, increased excrement and oxygen consumption, and the highest physiological requirements. In the actual breeding, during this period, the method of mixing water or changing water once every three days is adopted to keep the goldfish in the best feeding state with clear water and sufficient oxygen.
Goldfish with water temperature of 15 ~ 18℃ have moderate food intake, normal activities and the longest shelf life of water quality, which is a relatively easy stage for goldfish to manage.
3. The goldfish is very gentle, and there will be no phenomenon that big goldfish chase small goldfish. In addition to the breeding season, goldfish of various shapes and colors can be mixed together.
4, feeding must be strictly timed quantitative, keep the water fresh. Generally speaking, the feeding frequency should be 1-2 times a day,/kloc-0 times in the morning and evening, and/kloc-0 times in the evening. In addition, the time, frequency and quantity of feeding should be determined according to the following principles:
(1) When the weather is fine, the daily warm air is mild, the dissolved oxygen in the water is sufficient, and the water temperature is suitable, you can throw more bait appropriately.
(2) When the water quality is thin and the fish has a big appetite, you can feed more.
(3) If the fish is sick, or the species is delicate and precious, throw less coarse bait and throw some fine bait instead.
In order to distinguish the saturated digestion and absorption of goldfish, it can be distinguished according to the color of fish manure. Green, brown or black fish droppings indicate that fish are suitable for feeding and well absorbed. If the fish manure is white, it means that the fish is full. The residual bait should be cleaned up in time.
When your fish tank is very small, you should pay special attention to filtration and oxygenation.

Method for cultivate silver ingot fish
Acer truncatum Bunge, commonly known as Acer truncatum Bunge, Blood Parrot and Fortune Fish. Its whole body is bright red, plus its chubby figure and soft fins, which is really lovable. Breeding techniques are summarized as follows.
1. Water quality requirements
Acer truncatum likes soft water with weak acidity and low hardness. Due to congenital inability to close the lips, the ability to control water flow is poor, and the water flow through gills is small, so the ability of water flow to exchange oxygen with gills is much worse than that of its parents and other fish. Therefore, the water body for raising Acer truncatum must have sufficient oxygen. Aquarium is best equipped with biochemical filter cotton, water pump and oxygen-increasing aeration equipment. The specific indicators are PH 6.5 and dissolved oxygen 8 mg/L. ..
2. Temperature control
Acer truncatum has strong adaptability to temperature and can live freely in the water temperature of 20 ~ 30℃. However, Acer truncatum is quite sensitive to temperature. When the water temperature is low and the water temperature changes dramatically, it is easy to produce stress reaction, leading to dim body color, loss of gorgeous luster, and even black stripes or markings. It is best to keep the water temperature in the range of 25 ~ 28℃ during feeding, and the temperature difference between water temperature before and after each water change should not exceed 0.5℃.
3. Feeding management
Octopus is an omnivore. It eats almost everything such as artificial bait, flakes, granules, red worms, bumper shrimp and water lice, and it is quite greedy, so it is easy to feed octopus, but it is not easy to raise a robust and colorful octopus. Feed the bait regularly and quantitatively every day, reasonably match the bait nutrition, feed the fresh shrimp and small fish regularly, and it is best to choose artificial bait specially prepared for silver carp, such as Bao Jianhong, Rama Hong, Bao Li, etc. This kind of feed added with carotene such as astaxanthin and D is not only convenient, but also makes the body color of silver carp more bright and beautiful.
4. Disease control
(1) bacterial diseases. Symptoms are redness and swelling of gill filaments. In severe cases, gill filaments are white and bleeding, eyeballs are swollen and turbid, abdominal swelling is stagnant, and the skin around reproductive holes is congested and swollen. The sick fish floated feebly on the water and could not sink. The treatment method is to soak in 150ml/m formalin solution for one hour, and then completely change the water. You can use it again in two days. At the same time, the fish were fed bait, and erythromycin was mixed in the bait at a dose of 50 mg per kilogram of fish every day for three weeks.
(2) mycosis. This disease often occurs in the alternating season of autumn and winter. Some small wounds on the surface of fish are infected with mold, and gray and fluffy water mold is attached to the wounds. The treatment method is 1 mg/L soaking, and the water is completely changed the next day.
(3) Parasitic diseases. This disease often occurs in autumn and winter and alternate seasons of spring and summer when the water temperature changes dramatically. The diseased fish are covered with white spots, which will cause many bacterial diseases after a long time. The treatment method is to soak in 0.3 ~ 0.5 mg/L copper sulfate solution for 24 hours, and then replace 1/2 water.
Feeding colored feed in critical period
You may know the origin of this fish. It is the first offspring (F 1) obtained by Azar's father and his mother with purple crater, but do you know that every fish is distinguished by its mouth shape, head back and body color, but none of them are exactly the same! !
After the young Acer truncatum was born, it did not have any characteristics of Acer truncatum, but it was a bit like the general cichlids in Central and South America. After about 20 days' feeding, the appearance of the small octopus will gradually change, the muscles of the head and back will gradually swell, the thickness will begin to increase, and the body color will gradually change from striped black to gray silver. At this time, the red pigment in the octopus has begun to accumulate and proliferate, but at this time, the color of the small octopus about 3 cm is not red, and it will not appear until about 50 days after birth and about 5 cm in size.
It is suggested that the owner feed them with "coloring feed" at this time, which can not only fully provide the nutritional needs of the small octopus, but also accelerate the octopus to turn into lux as soon as possible. During this period, if abalone is not properly cared for in nutrition and its body color does not turn red, then it is not necessary to expect it to become a "swan" one day, because this is an important critical period to determine its body color.
Editor's summary: Don't think that octopus won't "move" just because it often lives in Taiwan Province Province. Fish are very adaptable and not picky about food. The average fish will gobble up the fish. Of course, we'd better change the water for silver carp with weak acid soft water, because silver carp will grow better in this environment and its fertility will be enhanced.
