Angel fish
Angel fish are A kind of cichlid, it can be said to be the representative fish of hot fish. The dorsal and pelvic fins are very long, very much like the spread feathers of an angel. What should we pay attention to in the growth of angel fish?
1. Water quality to avoid contamination
Do not feed bait for artificial incubation to avoid contamination of the water quality; especially live bait! Water fleas, a type of water flea mixed with water fleas, can penetrate the outer wall of fertilized eggs and greatly reduce the hatching rate of fish eggs!
2. The purpose of artificial growth
The main purpose of artificial growth is to reduce the consumption of broodstock when caring for eggs after spawning, so that broodstock can resume spawning faster, and to avoid the process of broodstock taking care of eggs. Growth may be hampered by eating fish eggs by mistake due to hunger.
3. Signs before spawning
Carefully observe the successfully matched Pisces. If the area around the anus begins to protrude, that is, the vas deferens and ovipositor begin to droop, this is before spawning. If there are signs, they will choose an area they think is safe before spawning, and jointly defend the territory and repel intruding fish.
4. The environmental area is clean
Before spawning, choose an area that is considered safe. This territory may be a field of aquatic plants when it is born, and it may be a field of aquatic plants when it is raised artificially. In the corner of the aquarium glass, after determining that the environment is safe, the male and female fish will peck the spawning area clean.
5. Growth status
After the female and male fish peck the spawning area clean, the female starts to lay eggs, and the male fish starts to lay eggs at the same time as the female fish lays eggs. Fertilization is held. Under normal circumstances, the entire spawning process will last for several hours, and the number of eggs depends on the size of the adult fish, generally ranging from 400-1,000.
6. Growth status of swallowfish
After the egg protection process, the swallowfish larvae begin to hatch, but they still cannot swim. They rely on the local area to absorb their own vitellin for a long time. They begin to swim away from the spawning point in 4-5 days and feed on weak water fleas. The male and female fish still take great care of the larvae.
7. Avoid being overly frightened
Don’t wait until the swallowfish shows signs of spawning.Put them into another aquarium for growth and raise them alone. At the same time, use an air pump to help provide sufficient dissolved oxygen in the water. It is not appropriate to use too strong lighting at this time, and it is not appropriate to make them too frightened. Being too frightened will lead them to swallow everything. Fish eggs that were once laid.
