The Marine Elf Nemo Family-- A complete Collection of the Culture of "Clownfish"
Clown fish is a common name for the fishes of the subfamily Sparidae, which is a kind of tropical saltwater fish. It is known that there are 28 species, one from Premnas and the other from Amphiprion. Clown fish and sea anemone have a close symbiotic relationship, so it is also called sea anemone fish. The poisonous anemone protects the clown fish, while the clown fish eats the digested residue of the anemone, forming a mutually beneficial symbiotic relationship.
The clown fish has a maximum body length of 11cm. The total number of dorsal spines is 10: 12; the total number of dorsal soft strips is 4: 16; the total number of gluteal spines is 2; the total number of anal fin soft strips is 14: 15, all juveniles are black with scales concentrated blue; white patches on the forehead and upper side; all fins are black except the outer part of the pectoral and soft dorsal fins. The geography of the adult fish and the behavior color is variable.
Clownfish are not the only hermaphrodites, but they are one of the few species in which males can become and females cannot become males. Each clown fish population has a dominant female and several adult males, who are hermaphroditic in adolescence. If the dominant female dies, one of the adult males will undergo hormonal changes and become the new female in the population. During the spawning period, male and female fish have the domain behavior of protecting nests and eggs. One end of the egg will be fixed to a stone and hatched for a week or so, and the young fish will float in the water for a period of time before they inhabit symbiotic organisms such as sea anemones. Because there are one or two white stripes on their faces, like clowns in Beijing Opera, they are commonly known as "clown fish".
Environment: reef fish; non-migratory; non-migratory; ocean; upper and lower limit of depth 1m-55m
Climate: tropical; between 25 degrees N and 35 degrees S.
Importance: fishery, low economy; aquarium, commercial.
Resilience: height, population doubling time less than 15 months
Biology: inhabiting coral reefs and reefs, juvenile fish often symbiosis with large sea anemones, sea urchins or small coral tops. Form small to large schools of fish with stomach contents including algae, copepods, and other planktonic crustaceans.
Mode of reproduction: egg placement.
Diet: omnivorous.
Clownfish are native to warmer waters in the Indian and Pacific oceans, including the Great Barrier Reef and the Red Sea. Although the distribution of most species has its limitations, some of them are widely distributed. Clown fish live in shallow lagoons or coral reefs at the bottom of shallow waters. Indo-Pacific Ocean, Red Sea, north to southern Japan, south to Australia, Sydney and so on.
The clown fish has special mucus on its body surface, which can protect it from the influence of sea anemones and live safely and freely. Because of the protection of the sea anemone, the clown fish can be protected from other big fish. At the same time, the leftover food of the sea anemone can also be supplied to the clown fish, and the clown fish can also use the tentacles of the sea anemone to build nests and lay eggs. For sea anemones, the free entry and exit of clown fish can attract other fish and increase the chance of predation; clown fish can also remove the necrotic tissue and parasites of sea anemones, and because the swimming of clown fish can reduce the deposition of debris into sea anemones. Clown fish can also remove parasites or mold from their bodies by rubbing between the tentacles of sea anemones.
Clown fish lay eggs in the tentacles of sea anemones. After hatching, the young fish live in the water for a period of time before they begin to choose groups of anemones suitable for their growth. After adaptation, they can live together. It is worth noting that clown fish can not live in every kind of sea anemone, but only in specific objects, while clown fish can still survive without sea anemones, but lack protection.
Clownfish are very domain-minded, and usually a pair of male and female fish occupy a sea anemone to prevent other species from entering. If it is a large sea anemone, they will also allow other young fish to join in. In such a large family, the strongest is the female, she and her mate, the male, dominate, and the other members are males and young fish that have not yet shown their characteristics. Females chase and oppress other members so that they can only move in unimportant corners around the sea anemones. If the female fish in charge disappears, the male of the original couple will become a female within a few weeks, with full female physiological function, and then take longer to change external characteristics, such as body shape and color, and finally completely become a female, while one of the other males will produce the strongest one to become her mate.

Habits: inhabit shallow coastal coral reef areas with a depth of 3 to 25 meters, usually living in strong current areas with a depth of about 15 meters. Each anemone is captured by a larger female, along with a smaller functional male (functional male, meaning a fish that only provides male functions but whose sex is not permanent, because it can change its sex as needed) and several young fish whose growth is hampered. If the female is driven away or leaves on her own, the functional male will be transformed into a female, and the largest juvenile will assume the role of functional male over and over again.

The Indian Ocean Silver Joker is very similar to the Pacific Silver Joker (Amphiprion sandaracinos) except that the leucorrhea of the latter extends back from the upper lip, while the upper lip of the former is consistent with the body color and is not difficult to tell.
The reproduction of clown fish
First of all, it is necessary to have a more suitable cylinder, in which to put a few more living rocks, there should be a certain place of shelter, that is, the role of barrier. It is best to put a pebble in this escape cave, outside the mouth of the cave, where the pebbles are attached, and a larger sea anemone, which is best able to cover the whole hole or cover the pebbles when you grow up. It is recommended to choose a large carpet sea anemone, or a princess sea anemone, so that the clown has sense of security. In addition, the hole should also ensure that there is a suitable flow of water through.
The next step is to choose the clown, it is recommended to choose the smaller male fish, the general red clown male fish is bright red, choose 1 Mel 2. Then choose to remind larger, abdominal gonadal mature female fish, the general red clown female is dark red, 4 Mel 5. Keep them together for a period of time and observe the pairing.
In general, most of the matched clowns are a couple cooped up in a sea anemone, while other clowns are driven aside. If you find this at this time, you can remove the other clowns. Pay attention to the regular feeding of clown couples and pay attention to nutritional matching. VG- microbial nourishing agents can be mixed with vitamin E in their bait.
During the period of clown fish spawning, the phenomena that occur are:
The main results are as follows: 1. when the gonads of female and male fish mature, the mating period of male fish and the fallopian tube of female fish will be prominent.
2. When the day of spawning is approaching, the clown couple will take the initiative to tidy up the environment of their love nest and use their mouth to sweep away algae, gravel and so on. Ha ha
3. Clown fish usually spawn in the afternoon or near evening, about 2 hours, and the number of eggs laid each time is hundreds to thousands.
4. After the female fish spawn, the male fish will release sperm immediately and alternately until the end of spawning.
5. the fertilized egg has a transparent adventitia and an orange yolk.
6. In the process of clown eggs hatching, the clown couple will blow each other by mouth or through the pectoral fin and caudal fin to get out the dirt on the eggs, so that the eggs are fully exposed to oxygen, and the males are generally more diligent in the later stage.
7. The eyes in the oocyst can be clearly seen in about 10 days, and they can be hatched in 14 days.
8. After hatching, the small fish is very fragile and has a strong ability to avoid light, so it is necessary to leave his parents and avoid the current, but adhere to the regular change of water, pH and temperature should be stable.
9. Hatched fish can be fed with rotifer and VG once a day. After 5 days, rotifers and newly hatched shrimp can be fed twice a day. After 15 days, you can feed the harvest shrimp alone, and a month later, you can feed a small amount of clam meat.
As long as you give the clown a good environment, as the saying goes, "full of warmth and lust", take good care of, natural reproduction will be fine. I hope everyone's clowns will be full of children and grandchildren!
Ha ha! All right, that's all for today's clown fish!
