What are the common diseases of tropical fish parrot fish? What if there are white spots on the body?

Parrot fish, commonly known as parrot fish, parrot fish, red cuneiform sea bream and so on, are tropical fish living in coral reefs. It gets its name because of its colorful and parrot-shaped mouth. In addition, there is a kind of freshwater watching fish bred by the American sea bream male red devil fish and purple red fire mouth, which is also known as the blood parrot because of its bright red body color. So what are the common diseases of parrot fish? How to do with white spots on the body? According to the data, the pathogen of white spot disease is many-bearing melon worm. After the small melon worm invaded the skin of the fish, the skin mucus of the diseased fish increased, and a dense layer of white spots could be seen on the pectoral fin, dorsal fin, caudal fin and body surface skin. In the early stage of the disease, the diseased fish gathered in the cylinder corner to rub against each other. In the later stage of the disease, the diseased fish floated dully on the water surface and did not feed. Due to the physiological characteristics that it is difficult for melon insects to reproduce when the water temperature is above 25 ℃ and begins to die at 28 ℃, the water temperature can be slowly raised to 30 ℃. After a few days of resting, the cysts of melon insects begin to fall off, and the diseased fish can recover by changing new water in time. You can take the medicine-- "clean at a time". What you need to remember is to pay attention to the dosage.

Parrot fish also have the following common diseases: enteritis and anal prolapse.

1. Parrot fish bacterial enteritis is mainly caused by eating unclean food or overeating, intestinal distension and obstruction of excretion, and finally enteritis caused by bacterial infection. The pathogen is Aeromonas punctata. [symptoms] diseased fish often have a dilated abdomen, erythema, protruding anus, dull fish, motionless in the corner of the aquarium, short-term convulsions of body muscles, no food, and white feces. Open the abdomen of the fish, you can see hydrops in the abdominal cavity, congestion and inflammation of the intestinal wall, light cases, only part of the intestines appear red, in severe cases, the whole intestine is purplish red, there is no food in the intestines, filled with yellowish mucus and blood pus.

There are many ways to treat enteritis. There are also many drugs sold in the market, such as nanobacteria, Yufukang, sulfa guanidine, etc., and external drugs, such as bath fungus, furacilin, gentamicin, oxytetracycline, dysentery and so on, can achieve better results after dilution.

2. Parrot fish protrude the anus, mainly protruding at the entrance of the anus, showing white intestines outside the anus, like a caterpillar. It is very dangerous when this happens to parrot fish. If the parrot fish is found to have this kind of prolapse of the anus, it must be treated in time. Generally speaking, parrot fish prolapse is mainly due to long-term feeding of single food or excellent food, such as long-term feeding of dried shrimp that is not soaked; there is also a pathological prolapse of the anus, a slight prolapse caused by food. At this time, parrot fish can be fasted for a period of time, but it is worth noting that after the anal gland is taken back, it is still necessary to fast for a week to avoid recurrence, resulting in habitual prolapse of the anus. If it has been prolapse for a long time, you need to look at the fish for medicine. You can choose 4 tablets of furazolidone (dysentery) + benazepril + 31 degrees water temperature + stop eating, dissolve in an aquarium of 1 meter, and change it into a 3-water tonic in 2 days. You can recover after a week of medication.

PS: is the parrot fish poisonous?

The parrot fish itself is not poisonous, but some of its food is poisonous. The parrot fish has organs that break down and digest toxins, so the parrot fish will not be harmed by these toxins. But if the parrot fish is caught at this time and the toxins in its body are not completely removed, then the toxins in the parrot fish food will be transferred to humans who eat parrot fish. Therefore, many fishermen advise greedy diners not to eat parrot fish.
