Why don't rich fish eat when they lay eggs?

Fortune fish is also called (blood parrot, feng shui fish)

The scientific name of fish is blood parrot. Because of its red color, plump figure and smiling face, it has been called "rich fish" by many people in recent two years. After changing a more attractive name, more and more people bought it, and some vendors used other fish to pretend to be "rich fish" through dyeing technology. As long as you feed an imported red feed, the fish will turn red slowly, but once you stop taking the medicine, it will still fade. So, I want to remind you here that you should be more careful when buying rich fish.

Family and species: cichlidae

Blood parrot, also known as rich fish, has a short body, a short head, a high back, a round abdomen, a generous body and a body length of more than ten centimeters. The tail handle is short, the tail fin is cut, and it has a parrot-like face. Body color from small to large, from deep to light, gray, grayish white, pink, orange red, adult fish is blood red. His posture is clumsy, but he is red and happy, but he is also pleasing.

Feeding mode:

In the disease management of blood parrot, water quality factors and physiological structure of blood parrot should be considered. These two key points determine the health, body shape and body color of the blood parrot. Before talking about disease treatment and management (including medication), let's start with the most basic prevention and management. After all, the phrase "prevention is more important than cure" cannot explain the role played by this concept in aquatic organisms again and again. Especially for this kind of fish with congenital "defects" in physiological structure, it is best to ask for medical treatment and medicine when fish diseases occur, so as to avoid the chance of pathological changes as much as possible!

Water quality factor

In addition to several key points mentioned in water quality management (discussed in detail above, not repeated here), the most important thing is the "mentality" of water quality management. It has been clearly stated in the article and general feeding management experience that "blood parrot" is a kind of fish that is taken care of very well and is very "resigned", and it is definitely not the kind of Jiao Jiao woman who needs to spend a lot of time and energy to take care of it. As a result, there are many ridiculous jokes about spitting rice: "Does the parrot need to change water?" "My blood parrot hasn't changed water for eight months. What about yours? " "Blood parrot want to live can live. Did that genius raise the blood parrot to death? " Of course, there is also a sneer at the death of the blood parrot. Now let's put away these contemptuous thoughts and face up to the pathological problems that blood parrots may face.

Bacterial disease

This pathogen mainly invades two parts of the blood parrot, one is the gill and the other is the digestive tract. In the aspect of branchial diseases, the author thinks that it is the biggest health problem of the blood parrot, because once bacterial infection invades the branchial region of the blood parrot, the branchial silk becomes red and swollen until it is ischemic, white and broken, which is almost a series of reactions, and finally it will cause quite common fish albinism and a large number of deaths. In addition, this disease often invades the eyes of fish, causing diseases such as exophthalmos and turbidity.

As for the impact on the digestive tract, when pathogenic bacteria (not necessarily the same bacteria that invade the gills) invade the gastrointestinal tract, the abdomen will be full of water (gas), and the symptoms of genital pores and nearby skin congestion and redness are quite common. This kind of sick fish often can't sink smoothly and will float near the water surface.

Fungal invasion

In this respect, dermatophytes and saprophytes are usually parasitic. In autumn and winter, when the fish has some small wounds and the water quality is relatively good, it is a very common disease.

Parasitism of protozoa

The main parasite is the white spot worm in the fiber worm. This single-celled parasitic animal will appear in autumn and winter and spring and summer when the water temperature changes dramatically. In addition to the formation of quite dense white spots on the body surface, there will be quite a variety of bacterial diseases.

Endemic diseases that are still controversial

What I want to mention here is the head hole disease of cichlids (especially cichlids in Central and South America). Although some "experts" claim that this disease is caused by flagellate parasitism, there is no direct evidence in academic circles at present! To be sure, this disease is more serious in some aquariums or pools with fairly good water quality.

Or the fish you said is a lucky fish (also called warship fish).

This fish is oval. Whole body is golden yellow. The scales on the body surface have a faint red edge and a metallic luster. Big head, big mouth The pectoral fin is wide and golden yellow; The dorsal fin is low in front and straight in back; The gluteal fin extends from the posterior abdomen to the caudal stalk; The dorsal fin, gluteal fin and caudal fin are golden yellow, and the adult fish is 30 ~ 40 cm long, and some can reach 60 cm.

Ancient warships originated from rivers and lakes in sunda islands, Southeast Asia. However, because this fish is an extremely important food variety in Southeast Asia, it is widely cultivated. So at present, they can be seen almost everywhere in Southeast Asia. This kind of fish can be said to be extremely easy to raise. There is almost no difficulty. Weak acid, neutral and weak alkaline water can adapt. But I prefer weak acidity to neutral water quality. The required temperature is 23-28 degrees. This kind of fish was once classified as snakehead. Now it is classified as olfactory gland bass. It used to be thought that there was only one genus and one species of olfactory gland bass. But in recent years, it has been found that there are two other new species of this genus. In their country of origin, they are very important food fish. Many fish farms are raising them. So we hardly have to worry about its source. This kind of fish belongs to super fish. And the growth rate is extremely fast. Can become very huge in a very short time. So be careful not to put it in a relatively small aquarium, which should be no less than 120 cm. Otherwise, it will adversely affect their growth.

Warships are omnivores. They prefer green food. But this does not affect their swallowing of small fish and shrimp. They like to eat live fish and shrimp. These high-protein foods can play a good role in their growth. Therefore, when feeding ancient warships, we must pay attention to the feeding of plant feed and must not lose the feeding of animal feed.

Ancient warships were generally impossible to breed in aquariums. But if you have a big swimming pool, you can try it. They are typical climbing perch that breed in nests. The head of the male warship has a bulge like a goose. The head of the female warship is relatively smooth. Therefore, male and female identification is generally not difficult.
