Clown fish
The clown fish is petite and colorful, and is very popular among aquarists. Compared with other saltwater fish, it is easier for clown fish to grow artificially. Generally speaking, the growth and maintenance of clownfish include spawning, hatching, growth of young fish, and feeding.
The growth process of the clown fish is not simple. Before laying eggs, the clown fish will diligently clean up the nest environment. , they generally lay eggs from afternoon to evening; during the hatching process, clown fish will remove dirt on the eggs; you can see the eyes in the egg sacs about 10 days after laying eggs, 10-14 It can be hatched within 3 days; the larvae are very fragile when hatched and have strong phototaxis. Therefore, it is necessary to move the parent fish, close the water flow, and ensure adequate water changes. The pH and temperature should not change too much. As food for the larvae, after birth, use rotifers plus VG, once a day; after 5 days, use rotifers plus newly hatched new year shrimps, twice a day; after half a month, use all new year shrimps.
Clown clown fish need enough space and immersion when spawning, and they will clear the land before spawning . Spawning time is generally from afternoon to evening and lasts about 2 hours. After spawning, it is a critical step in the growth process of clown fish, hatching. Clownfish eggs usually hatch in the dark. Within two hours after turning off the lights, the eggs hatch. If the fish tank is not dark enough, the young fish may be stillborn. During the hatching process, the male and female fish blow each other's mouths or use their pectoral and tail fins to shake back and forth to remove dirt on the eggs and allow the eggs to be fully exposed to oxygen. The males work harder in the later stages. The incubation period of clownfish takes seven to ten days. The water flow needs to be reduced before hatching to avoid the water flow being too strong and damaging the tender young fish.
Young fish that hatch well need to be transferred to a breeding tank. The newly hatched seedlings are so fragile that running water can injure them. Therefore, when catching and releasing young fish, be sure to handle them gently and avoid whirlpools. When placing the young fish into the cultivation tank, pay attention to immersing the solution of the young fish in the water.Then slowly turn the container out, never pouring the young fish into the tank. Changes happen most fortunately darkly, as they adapt to new circumstances.
Naturally, in order to increase the growth rate, we also need to master some growth skills. The clown fish is extremely sensitive during the estrus period. It is fierce and needs a quiet and hidden space during the spawning period. Therefore, one of the growth methods of the clownfish is to remove the paired clownfish and sea anemone alone.The clown fish will lay eggs in 1-2 months. The hatching of fertilized clown fish eggs begins after sunset and begins hatching 1-2 hours after the lights are turned off. If the lights are not turned off, the eggs will not hatch and will be sacrificed. Since the larvae are at risk of being swallowed by the parent fish, they need to be separated from the parent fish after hatching.
The second growth method of clown fish is to use a small water pump to reduce water circulation, which can promote the hatching of larvae. Before the larvae hatch, sufficient water flow must be provided to the eggs. However, the newly hatched larvae are very weak and will be beaten to death if given the slightest stimulation. Therefore, after hatching, it is necessary to stop the water flow as much as possible.
The third growth method of clown fish is the still water method for raising larvae. At night, a 40-watt fluorescent lamp is installed at a position 0.5 meters above the water to keep the lights on all night. The water temperature when raising in running water is 25-29 degrees C. There is usually no need to change the water.
