What to Do When Parrotfish Develop White Spots? Common Disease Prevention and Treatment Methods for Tropical Fish
Parrotfish, commonly known as parrot cichlid, parrotfish, red wedge cichlid, etc., are tropical fish that live in coral reefs. They are named for their brilliant colors and mouths that closely resemble a parrot's beak. There is also a freshwater ornamental fish bred by crossbreeding the male red devil cichlid (a Central American cichlid) with the purple-red firemouth, and because of its bright red body color, it is also called the blood parrot. So what are the common diseases of parrotfish? What should you do when white spots appear on the body? According to data, the pathogen of white spot disease is Ichthyophthirius multifiliis. After Ichthyophthirius invades the fish's skin, the diseased fish's skin mucus increases, and a dense layer of white spots visible to the naked eye appears on the fish's pectoral fins, dorsal fin, caudal fin, and body surface skin. In the early stage of the disease, the diseased fish gather in the corner of the tank and rub against each other. In the later stage of the disease, the diseased fish float sluggishly at the water surface and do not eat when food is offered. Because Ichthyophthirius does not reproduce easily at water temperatures above 25 degrees C and begins to die at 28 degrees C, the water temperature can be slowly raised to 30~31 degrees C; after resting for several days, the Ichthyophthirius cysts begin to fall off, and if the water is replaced with fresh water in time, the diseased fish can recover. You can use the medication —— “White Spot Once Clean”; remember to pay attention to the dosage.</span></p> <p style="text-align: center;"><span style="line-height:1.6; text-indent:2em"></span></p> <p style="text-indent:2em;">Parrotfish also have the following common diseases: enteritis and prolapsed anus</p> <p style="text-indent:2em;">1. Bacterial enteritis in parrotfish is mainly caused by eating unclean food or overeating, with the intestines becoming distended and excretion blocked, and finally bacteria infecting the intestines and causing enteritis. The pathogen is Aeromonas punctata. [Symptoms] The diseased fish often has a swollen abdomen, shows red spots, a protruding anus, and the fish body becomes sluggish, staying motionless in the corner of the aquarium, with short bouts of twitching of the body muscles, no feeding, and white feces. When the fish's abdomen is cut open, abdominal fluid can be seen, and the intestinal wall is congested and inflamed. In mild cases, only part of the intestine appears red; in severe cases, the entire intestine is purplish red, with no food in the intestine and filled with pale yellow mucus and bloody pus.</p> <p style="text-indent:2em;">There are many methods for treating enteritis. There are also many drugs sold on the market. Oral drugs such as nakexin, yufukang, sulfaguanidine, etc., and external drugs such as yujunjie, furacilin, gentamicin, oxytetracycline, furazolidone, etc., after dilution, can be splashed or used as a bath, and all can achieve relatively good results.</p> <p style="text-indent:2em;">2. Prolapsed anus in parrotfish mainly involves protrusion of the anal opening, with white intestines exposed outside the anus, like a caterpillar. When parrotfish show this condition, it is very dangerous. If you find that a parrotfish has this kind of prolapsed anus, you must treat it promptly. Generally speaking, prolapsed anus in parrotfish is mainly due to long-term feeding of a single food or food that is too hard, such as feeding dried shrimp that has not been soaked soft for a long time; there is also a pathological type of prolapsed anus. The mild prolapsed anus generally caused by food can be addressed by fasting the parrotfish for a period of time, but it is worth noting that after the anal gland retracts, fasting is still needed for about a week to avoid recurrence and the development of habitual prolapsed anus. If the prolapsed anus has already persisted for a relatively long time, then medication should be used according to the fish's condition. You can choose 4 tablets of furazolidone (furazolidone) + Baibichu + 31 degrees C water temperature + stopping food, dissolved in a 1 m aquarium, change 1/3 of the water every 2 days and replenish the medicine. After one week of medication, it can recover.</p> <p style="text-align: center;"></p> <p style="text-indent:2em;">Appendix: Are parrotfish poisonous?</p> <p style="text-indent:2em;">Parrotfish themselves are not poisonous; it is just that some of the food they eat is toxic. Parrotfish have organs in their bodies that break down and digest toxins, so parrotfish are not harmed by these toxins. However, if people catch parrotfish at this time and the toxins in their bodies have not been completely eliminated, then the toxins from the parrotfish's food will be transferred to the humans who eat the parrotfish. Therefore, many fishermen advise greedy diners not to eat parrotfish.</p>

Are rice field eels and loaches viviparous or oviparous, and do they belong to fish?
In rural rice paddies, more and more farmers are trying to farm rice field eels and loaches, these two slippery animals. So do the two belong to fish? Are they viviparous or oviparous? According to Peng Zifa, a rice field eel farmer in Ningxiang, Hunan, fish swim with fins, breathe with gills throughout their lives, and are vertebrates that live in water throughout their lives. The rice field eel meets these conditions and belongs to fish. "Shanyu" is a common folk name; the loach is also called "qiuyu" and is known as the "ginseng of the water." It lives in lakes and ponds and is a fish with very high nutritional value. It differs from other fish no matter in appearance, body shape, or living habits, and is a special kind of fish. In addition, because both belong to fish, they are both oviparous animals. <p style="text-align: center;"></p> <p style="text-indent:2em;">The rice field eel is a bottom-dwelling fish living in freshwater. It requires a relatively stable living environment and likes to inhabit places with dim light, small water temperature differences, and little human disturbance. It likes to live in soft, humus-rich shallow water and still-water mud, living about 30 cm from the ground surface. The eel likes <span style="font-size:13px; line-height:1.6; text-indent:2em">to inhabit burrows, directly drilling holes without pushing soil outward. The burrow has two or even more openings, and there is another one specially used for reproduction called a breeding burrow, which is wider and more hidden. The burrowing behavior of the eel changes with temperature and water level, and the burrowing behavior of eels also differs by region and size.</span></p> <p style="text-align: center;"><span style="font-size:13px; line-height:1.6; text-indent:2em"></span></p> <p style="text-indent:2em;">No matter which farming method is adopted, such as cage, courtyard, factory farming, and soil-based or soil-free farming, the farming water level should be shallow, and fish nests or planted aquatic plants should be set up. Experiments have found that although eels without nests eat a lot, they move a lot and consume more energy; the opposite is true with nests. Therefore, it is best to adopt a semi-shaded healthy farming method, so that the eels eat more and consume less, thereby rapidly gaining weight and improving farming efficiency.</p> <p style="text-indent:2em;">The eel likes to eat fresh live bait and does not eat food that is unpalatable or rotten and deteriorated. It likes most to eat small fish, small shrimp, aquatic insect larvae, and the like, followed by terrestrial insects and earthworms. If river mussels and snails are shelled, it also likes to eat them very much.</p> <p style="text-align: center;"></p> <p style="text-indent:2em;">The eel's feeding method is the relatively rare suction-feeding type among fish, rapidly striking and swallowing prey within an effective range. If a certain bait has been fed for a long time, it is also relatively difficult to change its feeding habits, so wild eels should be trained with bait in a short period. According to this characteristic, an artificial compound feed that can be fed for a long time, has low cost, and gives a high meat gain rate should be selected. Where conditions permit, lights can be set up above the pond to attract insects into the pond for the eels to eat.</p> <p style="text-indent:2em;">The loach, however, is a small bottom-dwelling fish. It lives in still or slow-flowing water with a mud bottom and has strong adaptability, and can live in environments very rich in humus. When the water lacks oxygen, it can perform intestinal respiration, and after the water body dries up, it can burrow into the mud and lie dormant. It feeds on various small animals. It spawns in batches, and the main breeding period is from May to June. The fertilized eggs adhere to aquatic plants and hatch. The largest individual can reach 300 mm in length. Its flesh is excellent and it is one of the exported aquatic products.</p> <p style="text-align: center;"></p> <p style="text-indent:2em;">The loach likes to inhabit the bottom layer of still water and is often found in lakes, ponds, ditches, and the surface layer of mud rich in plant debris at the bottom of paddy fields. It has strong adaptability to the environment. The living water temperature is 10-30°C, and the most suitable water temperature is 25-27°C, so it should belong to warm-water fish. When the water temperature rises to 30°C, the loach dives into the mud to aestivate. When the water temperature drops below 5°C in winter, it burrows into the mud to a depth of 20-30 cm to overwinter.</p>
