Angelfish, the infamous Angel Fish, scientific name Pterophyllum scalare, is a representative species of cichlid fish. The cichlid fishes have a unique feature. They don't give birth to the next generation when they breed, and they have the nature of taking care of the next generation. However, when genital reproduction is extremely fearful of disturbing, if it is disturbed during pairing and breeding, the tragedy of eating eggs or small fishes will occur. Therefore, the environment that is not disturbed by external forces during the breeding of cichlids is extremely important to them. important.
First, the choice of fish lovers Want to breed angelfish, the first job is to pick the natural paired broodstock. If it is not he who chooses to match natural matches and artificially hardens the two fish to “send it as a pileâ€, not only is it difficult for them to give birth to the next generation, but it may happen that “looking at each other†and killing each other The situation. The selection of couple fish must take some time. At the same time, several female and male fish can be bred in a fish tank, and their behavior can be watched at any time; if two fish are found swimming often in pairs, they are divided into two groups. In the sphere of influence, when other fish come close together or break into their sphere of influence, they will work together to drive away the exotic fish. It is therefore possible to conclude that the two fishes have been paired together and can be used as breeding couple fish. After determining that the pair of angelfish have been paired, they can be moved to separate breeding troughs or removed from other unmatched fish to avoid the “new-marriage†“marriage†being disturbed by other fish. However, they affect the emotions of the next generation.
Second, the fertility situation in preparation for use as a spawning sink should be set up spawning cylinder, its role is to allow the broodstock can produce eggs on it. There are selling spawning cylinders on the market. They can also be replaced by hard plastic tubes, flower pots, etc., or they can be used as ovipositors. If no spawning device is provided, they will stick eggs to the tank wall of the fish tank. Prior to production, broodstock will be cleaned at their chosen spawning site and the contaminants on the spawning cylinder will be removed by mouth. Carefully observe the appearance of the fish, and if they find that their reproductive holes protrude outward, they are precursors that will be produced and will be produced in about two or three days. During spawning, the mother fish will first adhere eggs and eggs to the spawning cylinder (sticky eggs), and then the male fish will discharge semen on the eggs to complete the insemination work. The broodstock will then stay close to the fertilized egg and work together to care for the fertilized egg. They will use the pectoral and caudal fins to drive water near the fertilized egg, so that the flow of water near the fertilized egg is constantly renewal and with oxygen, and they will also pick themselves up if they encounter a whitened dead or sick egg. The number of eggs laid each time ranges from about three to four hundred grains to about one thousand grains depending on the body size and health of the broodstock. The fertilized eggs hatch about two to three days. The newly hatched small fish has a yolk sac on its abdomen to provide the initial nutrition of the fish and its swimming ability is still poor. At this point, the brooding fish join forces to guard the small fish. Occasionally, the brooded fish that are out of the group or falling will be returned to their original position with their mouths. When the yolk sac of the small fish is gradually digested, and the mouth can feed (about a week or so after hatching), it can be fed with freshwater shrimp without larvae or other plankton as the initial feed. Special attention must be paid to the fact that, as mentioned above, brooders must not interfere with external fertilization when they are watching the fertilized eggs and small fish! If they are disturbed, the broodstock may eat their fertilized eggs or small fish and cause the breeding to be abandoned. And it will be difficult for the broodstock that spawned or eaten to reproduce, because they will repeatedly eat their fertilized eggs or small fish and lose reproductive value.
Third, the small fish to take care of small fish in the hatching week or so can begin to feed plankton feed, and at this time should always pay attention to changes in water quality and adequate oxygen supply, and give the right amount (small meals) of bait. The fish are fed with plankton for about a month, and they have the appearance of common angelfish. They can slowly change their prey and change to bait for adult fish. After careful care for feeding for five to six months, the fish can grow up.
IV. Other Precautions If the fertilized egg or small fish is eaten in order to prevent broodstock from being stimulated, the broodstock may be removed immediately after the egg is fertilized. The fertilized eggs obtained should be slightly disinfected with drugs such as methyl blue or malachite green in order to prevent the growth of aquatic mold or other pathogens. After disinfection, the fertilized eggs should be incubated in a high oxygen content, clean water in the incubation tank, can also be given a trace of water. At any time, attention should be paid to picking out dead eggs that are albino or sick eggs of S. serrata in order to avoid affecting other healthy fertilized eggs.
