1) Don't feed rotting, dirty and infected things to the arhat fish;
A) Corrupt things: such as carrion, expired or wet feed, because the protein in such things has changed. This change not only destroys its own nutritional value, but also easily breeds bacteria, thus infecting fish.
B) Dirty and infected things: such as live fish and live red worms. Be especially careful when feeding live fish. Usually live fish have bacteria or parasites attached to their bodies and internal organs. Although they are not reflected in live fish, they are likely to multiply rapidly when the environment changes. This is equivalent to directly adding parasites or bacteria to the fish tank to infect the fish, so if you need to feed the small fish, you must clean it thoroughly.
2) Don't let it eat too much:
Many people like to throw some highland barley worms, even crickets, centipedes and other insects at the arhat fish. They all mistakenly think that these insects contain high protein, which is beneficial to the head development of arhat fish. In fact, this is wrong, because people have not considered whether protein can be digested and absorbed by arhat fish. The shells of these insect feeds are made of hard keratin, and these protein are like human nails and hair. Because arhat fish belongs to modern fish, it is still a mystery whether it can digest such protease. Undigested keratin or insect shells are likely to damage the digestive system and excretory system of fish and even cause various infections.
3) Don't let the arhat fish eat too much.
The health of fish is the same as that of human beings. Eat less, eat more and exercise more. It is best to feed the fish seven minutes full, or you can fast one day a week, so that the digestive system of the fish will not be under too much pressure. All of the above are effective methods to prevent enteritis. If Luohan fish is unfortunately infected with enteritis, it should be treated as soon as possible. This can be said to be not a disease, but it often happens to arhat fish. Shock is mainly caused by the fish touching hard objects violently during the activity, so that the fish may lie at the bottom of the tank for several days and cannot stand up. Because of the violent impact, some control nerves were damaged, and there is no specific medicine for thorough treatment at present. When encountering this problem, the water level in the fish tank should be lowered to the height where the fish normally stands, so as to reduce the pressure of high water on the fish, maintain normal filtration and correspondingly reduce oxygenation. Too much oxygen is likely to blister the skin of fish and take away all the sand and hard objects in the fish tank. Turn the fish over from time to time to prevent the fish from lying on one side for a long time to rot. If the fish is still eaten, you can feed it in moderation. It is best to prevent this situation, but in medical treatment, it can only be given a natural environment to recover slowly, and it should not be given drugs.
preventive measure
Don't put too many unnecessary hard corner decorations in the cylinder.
Don't play too crazy with the fish, because the fish can hardly see the glass aquarium, so it is easy for the fish to touch the glass when playing crazy.
Don't let the fish be unnecessarily frightened.
In addition, it is also necessary to check whether the fish are infected by parasites, because the fish are likely to be rubbed or scampered under the nuisance of parasites, which may lead to violent impact and shock. White spot disease is caused by melon parasitic on the surface of fish, which can be treated with Jingyu No.2 medicine. The fish's body surface, fins, eyes and gills are covered with small white spots of about 0.5 ~ 1.0 mm, and then they are damaged, festered and peeled off. This fish itches and itches. If a large number of gills are parasitic and mucus secretion increases, it will lead to dyspnea and suffocation and death.
All of the above diseases may happen to arhat fish. The so-called nip in the bud. During the period of raising arhat fish, you should pay attention to all aspects of hygiene and don't throw unclean things into the fish tank. The so-called disease from the mouth, a balanced ecological fish tank should not be sick. When raising and feeding, we infected the water quality and fish in the fish tank, and even made the fish sick. After the Luohan fish is sick, it is necessary to treat the fish disease as soon as possible, and it is not urgent. Everyone must understand that this requires a course of treatment, during which fish diseases may recur, but if the medicine applied is effective, the fish will gradually recover. Many times, fish can't be cured or even died because we are too anxious to cure fish diseases in a short time. We didn't consider that every disease has a course of treatment, and we went everywhere to find drugs to treat it, so we threw drugs indiscriminately and poisoned the fish. Everyone must understand that the mixed use of drugs must cooperate with each other. If used unreasonably, it is likely to produce high toxicity. At this time, the immortal is also difficult to save. This must be noted. When we want to change from one medicine to another, it is best to change one-third to one-half of the water, filter it with activated carbon, and absorb the residual medicine. Suggestion: If fish need to switch to new drugs, they should be given a two-day drug clearance period. Etiology:
(1) The water quality environment is poor.
(b) It is caused by surface damage.
(c) Subsequent parasitic infection with water flaccidity.
Symptoms: It seems that a substance similar to cotton is attached to the surface.
Treatment:
Heating is a good method.
Supplement antibiotics and antibacterial agents.
(c) Treating with malachite green or methylene blue.
