Juvenile juveniles, commonly known as blue circles
Transform into half of the sub-adult fish
Adult fish
The maximum body length of the Emperor Immortal in the wild state can reach 40 cm, and the appearance of juvenile fish (blue circle) is very different from that of adult fish, with a purple-blue background color mixed with blue and white circle-like markings. Until 1933, academics misjudged the juvenile fish of the Emperor Immortal as an independent fish, called Pomacanthus Nicobariensis. Studies have pointed out that and blue streaks (P. semicirculatus), six rooms (P. sexstriatus), blue-faced (P. xanthometopon）... And so on, large angelfish juveniles look very similar. The body color performance of the emperor immortal's juvenile fish can be regarded as one of the mimetic behaviors, simulating the behavior of the doctor fish, and some scholars believe that because the juvenile fish look completely different from the adult fish, it can reduce the attack of adult fish living in the same living place, which is conducive to growth. As he grew older, the white circle markings on the blue circle gradually faded and replaced by a yellow stripe, which was customarily called the circle emperor during this transition period, and the emperor's style was revealed.
As mentioned above, juvenile fish will help eat parasites, sponges, algae and any crustaceans of other large fish, and when they get older, they will feed on sponges and algae. In the artificial breeding environment, the Emperor Immortal (Blue Circle) can mostly accept a variety of feeds, such as artificial pellets, flake grains, dried shrimp, frozen shrimp, hair shrimp, of course, the most popular seaweed. However, if it is more than 10 inches of the emperor, it should be careful, perhaps because it is more partial to food, it is more difficult to change its eating habits in the artificial breeding environment (make it open), which depends on the careful care of the owner, the usual practice will stimulate his appetite with live bait, and it is also said that eating seaweed can help fish only discharge the drugs accumulated in the body during the capture and transportation process. In terms of feeding preparation, if it is a juvenile fish (blue circle), basically the two-foot tank can barely meet its needs, but due to the high requirements of the emperor immortals for water quality, especially the extreme sensitivity to the concentration of NO3, when the water quality changes, the emperor immortals are always the first in the whole tank to occur, and the watermark appears as a silent protest, so a mature environment for a filtration system is necessary. If you want to raise an emperor immortal into a fish, I believe that a three-foot tank will be more suitable, and try to use coral bones or biological stones to create a multi-point sheltered cave to avoid being hunted by old fish (other large seawater gods).
In fact, the emperor gods and immortals of the adult fish have good combat effectiveness, and when the war spirit is high, there will even be a 'grunting' sound to cheer up. In addition to its moving appearance and wonderful growth and change, the appreciation value of the Emperor Immortal is also an attractive place for its unhurried swimming posture, always with such a calm posture and exuding a menacing imperial demeanor. The processing procedures of the newly purchased Emperor Immortals are roughly the same as those of the general large-scale seawater immortals, and the designated actions such as constant temperature and water transfer should not be ignored, but it must be noted that the Emperor Immortals are very sensitive to drugs, especially in the first few weeks of the adaptation period is the most dangerous, in the days to come, if there is a need to drop the medicine, we must also pay close attention to its reaction and watch, in short, everything is careful. In addition, the annoying head hole is also a problem that often plagues the emperor immortals, and its incidence is higher than that of other large seawater gods, and the treatment of the head hole has been carefully described by LC Jun, which will not be repeated here. Only in terms of prevention should be as diverse as possible to provide a variety of foods and add Iodine in a timely manner, all of which may be helpful in preventing head holes. In terms of compatibility, the Emperor Immortals are by no means easy to match, and unless the size difference is too large or the health is not good, the Emperor Immortals can quickly find their own place in the fish tank. In addition, there are often questions about whether the emperor's immortals or their juveniles can be raised in coral tanks and whether they will bite corals... Yunyun, these questions do not have a definite answer, to know that the personality of each fish and the feeding environment of each fish tank are not the same, so it may be that the conditions of A are no problem, but in the fish tank of B it constitutes a disaster. My own experience is that 90% of the multicolored tube worm stone suffers, and other corals are like gambling waves, the opportunities for the upper and lower plates are equal, but the wins and losses are self-inflicted.
The emperor gods and immortals produced in each sea area have their own differences and are fascinating, and from the book literature, they will be generally divided into the Red Sea type (red tail, no sword) and the Pacific type (yellow tail/orange tail, with sword). However, due to differences in selling prices, the local market will have a more careful distinction between the places of origin, and the following are the characteristics and personal understanding of the emperor gods and immortals produced in some of the production areas. Pacific-Philippines; the most common source of origin on the market, the price is economical, the body color is blue, yellow tail, there is a sword, and occasionally a high-quality individual with tall straight stripes can be seen. Pacific- Indonesia/Bali; imports are second only to those produced in the Philippines, and the price is slightly higher. The body color is blue, yellow/orange tail, with a sword (there are also swordless individuals in the interval), and the overall standard is better than that of Filipino individuals. Pacific- Australia ; body color is similar to that of individuals produced in Indonesia /Bali , but the grain is fine, and juvenile fish ( blue circle ) are rarely imported , and the price is at a high level. Pacific Oceania (including tropical islands such as Guam and Tahiti); the body blooms with a velvet purple-blue glow, rarely imported, and the price is high, usually imported through Hawaii. Pacific - Dongsha Islands / Hainan Islands ; the source is usually fished by fishermen in the Dongsha Islands / Hainan Islands , which is also known as the "boat fish" in the Hong Kong Fish Music Circle. The body size of the captured individual is larger, I don't know if it is because of the frightening relationship of the capture process, the body color is mostly gray and dumb blue, and it may be able to show its true royal style again after the intimate care of the owner. Pacific - Christmas Island; The first thing to know is that there are two Christmas Islands in the Pacific Ocean, and the Christmas Island in the northwest waters of Australia is under the jurisdiction of Australia, in addition to the original indigenous people, the Chinese account for about 60% of the total population. One of the most well-known is the natural wonder of tens of millions of red land crabs flocking to the sea to lay their eggs every year from late October to November, but in recent years due to the impact of ant infestations (introduced by the Australian mainland), the number has dropped sharply, and the spectacular scene has disappeared. Because the island is surrounded by trenches , it forms a unique ecological environment and many native species or specialty fish species. Such as the cocoa centropyge Joculator, Centropyge eibli and Centropyge flavissima mixed zebra pattern miscellaneous batch, and so on. Another Christmas Island, located in the remote waters south of Hawaii , is one of the islands of the Kiribati Republic , which became independent from the British in 1978 , and the most popular Christmas Island Emperor is from the area. The body color of the Emperor of Christmas Island is also transparent with a velvety mysterious purple blue, set off by fine yellow stripes, and an orange tail, which is really like the emperor of the emperors. But I have also seen a Christmas Island Emperor with a sword and a yellow tail, but the proportion is small, it is worth mentioning that compared with other emperors produced in various places, the Christmas Island Emperor is more slender, and it depends on chance to meet the high-quality and high-body Christmas Island Emperor. Indian Ocean - Maldives/Ceylon; imports are small, similar in appearance to Indonesian products, but with a darker body color. Indian Ocean - East Africa; similarly very little imported, priced close to the level of the Emperor of Christmas Island, it has been observed to be taller, purple-blue in color, and swordless. Indian Ocean - Red Sea; in recent years, it has been imported less, with a grayish body color, no sword, fine lines and usually an orange-red tail.
