The Feed and feeding method of Fairy Fish
At first glance, the fairy fish has a small mouth, but in fact he is very cunning. When the fairy fish eats the bait, its mouth protrudes in the shape of a tube, sucking water into its mouth like a straw. His suction is very strong. Take the fairy fish 10 centimeters long as an example, he can inhale fish about 1 centimeter long in one breath. Grow to the largest size fairy fish had better not be raised together with small lamp fish, especially black shell shrimp, is a large size fairy fish plate food.
Silk @ # @ 254mm @
About 5 centimeters long, silk worms that live in the water often curl up in sewers and under sewers. He is silky and is the most suitable raw bait for juvenile and juvenile fish. Silk earthworms have the property of shrinking into a ball at once, so it is best to put them on a plate with a bottom, or install a hat-shaped bait box on the wall of the aquarium.
Red worm
Red worms, like silk earthworms, are baits with high nutritional value, which is the favorite food of the sea bream family led by fairy fish. However, compared with silk earthworms, red worms have a harder shell, and feeding young fish sometimes causes indigestion.
Water flea
From early spring to early autumn, water fleas will appear in water-precipitated ponds and rivers. Small crustaceans of about 1 mm are most suitable for juvenile and juvenile fish.
Water fleas spend the winter in the form of eggs, so they cannot be collected at that time. But when spring comes, a large colony of water fleas can be seen living on the water in the early morning. Unfortunately, there are very few places where such a scene can be seen. Water fleas consume a lot of oxygen and are difficult to transport or preserve, so this kind of bait is rarely used in aquariums. However, the fecundity of water fleas is very strong, as long as the species of water fleas are taken and put into water-filled tanks or plastic buckets, they can be collected naturally. Put it in a warm place in winter and sprinkle some milk powder as bait to breed throughout the year.
Shrimp in bumper year
Harvest shrimp is a kind of crustacean that lives in the sea. It doesn't look like a water flea, but looks like a small shrimp. Put the dry durable eggs in 20.3% salt water, keep the water temperature at about 25 ℃, keep the aeration action, and hatch in about 1-2 days. Young fish can be fed with a straw.
Artificial feed
Recently, due to the influence of river pollution and various conditions, it is becoming more and more difficult to get raw bait. It is believed that the main bait in the future should be artificial feed.
The advantage of artificial feed is that it is cheap and easy to preserve. If you feed artificial feed of good quality, then even if you feed raw bait, you can raise fish, especially the artificial feed sold on the market has been continuously improved in recent years. The quality is getting better and better.
Various forms of bait have their own advantages, but only for fairy fish, it is best to give priority to artificial feed, with fresh silk earthworms and red worms, and fish fry should be fed with adequate harvest shrimp, and the amount of bait should be best eaten at once, several times a day, at least once a day (twice a day).
When feeding, it must be noted that fish, like people, eat according to the principle of "eight percent full". If you feed too many fish, the body of the fish will be damaged, and the remaining bait will worsen the water quality.
Professional fish farmers in order to make the fish grow up faster, the secret of managing fish is to increase the amount of exercise of the fish, only feed the right bait, and pay attention to the fish all day long. Generally speaking, the rest of the players do not need to manage the fish so strictly, after all, it is just for the sake of being happy and nourishing their temperament.

Mud carp are omnivorous fish. four days after hatching, mud carp begin to feed on zooplankton, such as rotifers, copepods and small cladocera. After 10 days of hatching, the body length is more than 14 cm. In addition to eating zooplankton, they begin to feed on phytoplankton. After that, eat more and more phytoplankton, until about 40 days after the emergence, when the body length is more than 4 cm, they mainly eat phytoplankton. At the same time, mud carp like to lick and scrape the algae that grow on the surface of the underwater soil or rock. In addition, mud carp also ingest a small amount of zooplankton and organic crumbs.

Both new and old ponds must be cleaned and sterilized before releasing seedlings. The old pond should remove too much silt and retain a silt layer of 10 cm thick. Every winter, the fish species go through the pool or adult fish out of the pond, drain the pond water, clean up the sludge at the bottom of the pond and trim the pond foundation, so that the pond is exposed and cracked.
