How to breed fairy fish

Fairy fish, English name AngelFish, scientific name Pterophyllumscalare, belongs to the representative species of Sparidae. The fish of the family Sparidae have a characteristic that they will never give birth to the next generation unless they fall in love with each other, and they have the nature to take care of the next generation. However, fairy fish are very afraid of disturbance during reproduction, and if they are disturbed during pairing, it will lead to the tragedy of eating their own eggs or small fish, so it is very important for them to be free from external interference during reproduction.

First, the selection of couple fish if you want to breed fairy fish, the first job is to select the parent fish that are naturally matched. The selection of couples must take some time. Several females and males can be raised in a tank at the same time, and their behavior can be paid attention to at all times. If it is found that two fish often swim in pairs and delineate their sphere of influence, when other fish approach or break into their sphere of influence, they will work together to drive away exotic fish, you can probably conclude that the two fish have been paired by themselves. can be used as a breeding couple fish. After it is confirmed that the two fairy fish are paired, they can be moved to a separate breeding trough, or other unpaired fish can be removed, so as to prevent the "newlyweds" of the couple from being disturbed by other fish and affecting their next generation.

Second, the fertility environment should set up a spawning tube in the tank to be used for spawning, and its function is to enable parent fish to lay eggs on it. There are spawning tubes on the market, hard plastic tubes and flowerpots can also be used instead, or an aquatic plant with large leaves can be used as an ovipositor. If the spawning tube is not set, they will stick the eggs to the wall of the fish tank. The parent fish will clean the spawning site they have chosen before giving birth and use their mouth to remove the dirt from the spawning tube. Careful observation of the appearance of breeding fish, if it is found that their reproductive pores protrude outward, it is a sign that they will give birth, which will be produced in about two or three days. When spawning, the female fish will first attach the eggs to the spawning barrel (sticky eggs), and then the male fish will discharge semen on the eggs to complete the fertilization work. Then the parent fish will stay near the fertilized eggs and work together to take care of the fertilized eggs. They use their pectoral and caudal fins to drive the current around the fertilized egg so that the current near the fertilized egg is constantly updated and oxygenated, and they will pick out the albino dead or diseased eggs themselves. The number of eggs laid each time ranges from 300 to 400 to about 1000, depending on the size and health of the parent fish. The fertilized eggs can hatch in about two to three days. The newly hatched fish have yolk sac on their abdomen to provide the initial nutrition of the fish, and their swimming ability is still very poor. At this time, the parent fish will work together to protect the small fish, occasionally a small fish that is out of group or alone, and the parent fish will return it to its original position with its mouth. When the yolk sac of the small fish gradually disappears and can be fed (about a week after hatching), the nauplii or other plankton can be fed as initial bait. Special attention should be paid to the fact that, as mentioned above, external interference is strictly prohibited when parent fish take care of fertilized eggs and small fish. Once disturbed, the parent fish may eat the fertilized eggs or small fish, resulting in the waste of all previous efforts in this breeding. And parent fish that have eaten eggs or eggs will be difficult to reproduce because they will eat their own fertilized eggs or small fish over and over again.

Third, the care of small fish small fish in about a week of hatching can begin to feed plankton bait, at this time should always pay attention to changes in water quality and adequate supply of oxygen, and give an appropriate amount of bait (a small amount of food). When small fish are fed with plankton for a month or so, they will have the appearance of an adult fish. At this time, their bait can be slowly changed to the bait eaten by adult fish. After such careful care and breeding for five to six months, the small fish can grow up and mature.

4. other precautions if the fertilized eggs or small fish are eaten in order to prevent the parent fish from being stimulated, the parent fish can also be removed immediately after the egg is fertilized. Fertilized eggs obtained should be slightly disinfected with drugs such as methyl blue or malachite green to prevent the growth of water mold or other germs. The fertilized eggs after disinfection should be incubated in an incubator with high oxygen content and clean water quality, or a small amount of water can be given. And always pay attention to pick albino dead eggs or long water mold diseased eggs, in order to avoid affecting other healthy fertilized eggs.
