Question 2: What does the red nematode eat? If you want to feed some fish casually, ask them what they eat. Don't say eat mud, there is no mud, be precise, thank you! 1. Raise red nematodes. What should red nematodes eat?
There is no need to feed it, because it lives in the mud. If you eat it in the mud, the fish will have diarrhea.
2. Some people say that red nematodes eat fish feed? Really?
This is not true.
3. Also said that the added water should not exceed the red nematode?
If raised alone, don't exceed; But if you feed the fish, it depends on the water level!
4. How should peacocks raise small fish? Only egg yolk? I used to raise new fish and always died. Why?
The water temperature is about 26 degrees, but I raised it in summer. I didn't use warm water, but water that had been dried for 2 or 3 days. Fish don't need to be fed for a day or so, but are absorbed by egg yolk. Eggs can turn yellow the next day, but they go bad easily. The dead fish may be because of the water quality, which is too low!
5. Can they eat chopped red nematodes? How much should I cut?
You can't eat it the next day. It is too small. It will be ready in three or four days. Chop it into 1 and 2 mm pieces! ~~~~
Question 3: What should the red-line snake (red worm is also called red nematode) do if it wants to raise a large number of its own at home? Who can give me some advice? Especially what do red nematodes eat? Thanks to the aquatic organism commonly known as red nematode, also known as earthworm, its dry matter protein is more than 70%, and all kinds of essential amino acids are complete, rich in content and high in nutritional value. In addition, raising earthworms does not pollute the water quality and is the best live bait for freshwater fish and ornamental families. Do you want to raise them at home, farm indoors or dig holes in the yard?
Question 4: What does the red nematodes feeding fish in the fish tank eat? Nematodes live in sludge in clear flowing water and feed on microorganisms in filtered water.
Question 5: How to raise red nematodes? How much water should I add? Can I put it with the fish? Can red nematodes only use blisters? What does the red nematode eat? 1. Raise red nematodes. What should red nematodes eat?
There is no need to feed it, because it lives in the mud. If you eat it in the mud, the fish will have diarrhea.

Question 6: How do fish raise red worms? 5 minutes in the sand, the filtered water flow is moderate, similar to a manger, the pump pumps water to the left and the right falls into the water inlet of the pump, depending on its size.
Question 7: How to cultivate red nematodes, that is, artificially cultivate water worms?
(Professor Ansen Chen from Fujian Normal University)
First of all, briefly introduce the water earthworm.
Water earthworm (also known as silk earthworm, red nematode, ditch worm, etc. ) is the common name of annelids aquatic oligochaeta and an important part of freshwater benthic fauna.
Earthworms usually live in micro-flowing water and underwater sludge rich in organic matter. Where there is a lot of humus, there is often serious organic pollution and often lack of oxygen. In an anoxic environment, they stick out most of their bodies from the mud bottom and keep swinging rhythmically to promote the formation of water flow and facilitate the gas exchange of insects. The less oxygen there is in the water, the faster they swing. Once frightened, they all shrink into the mud. .
Like terrestrial earthworms, they devour the soil, ingest bacteria, organic debris particles and benthic algae from the soil at the same time, and sometimes feed on some micro-animals in the soil and excrete earthworm feces through * * *. Like temperature, the optimum water temperature is 25~28℃.
Some water worms (such as trematodes) can play a good self purification on sewage. Trematodes are very common in water. In a certain range, with the increase of pollution, its population also increases. In eutrophic water, the decomposition of organic matter consumes a lot of oxygen in the water, resulting in hypoxia in the water, and earthworms are relatively resistant to hypoxia. In such water, other creatures usually cannot survive or have few species. Due to the lack of competitors, these relatively anoxic earthworms multiply in large numbers. Therefore, some people advocate using the number of trematodes per unit area as an indicator of water pollution.
All kinds of water earthworms are very important decomposers in aquatic ecosystems, especially in eutrophic water bodies. They devour organic debris particles, humus and microorganisms in water and sediments, and are eaten by other organisms in the water (such as fish, frogs, snakes, turtles, etc.). Therefore, they play an extremely important role in the energy flow and material circulation of ecosystems.
Earthworms are hermaphroditic and fertilized by cross-fertilization. During mating, the front ends of two individuals are combined with the ventral surface, and each male hole discharges * * * into the other's seminal vesicle for storage. Exchange * * * and then separate. After the egg matures, the chain ring secretes mucus to form a banded egg bag (cocoon). The egg is laid in the egg bag, which moves forward to the hole in the seminal vesicle and flows out to fertilize the egg. The egg bag falls off from the front end of the body and sinks into the bottom mud. The openings at both ends of the egg bag automatically shrink and close into oval cocoons. The fertilized egg develops into a small earthworm in the cocoon. The time required for fertilized eggs to hatch young earthworms varies with water temperature and species, and the speed of growth and development varies with water temperature. The life span of earthworms is generally about 80 days, and a few can live to 120 days. Water earthworm is very prolific. Water earthworms, like terrestrial earthworms, have strong regeneration ability and can regenerate a complete individual quickly after being cut off.
Second, the introduction of common earthworm varieties
There are about 28 genera and more than 70 species of aquatic oligochaeta in China, belonging to 2 orders and 5 families. One is Plesiopora, such as Coccinellidae, Hydromyiidae, Hydromyiidae and Nematicidae, and the other is Prosopora, such as Earthworms.
In the breeding of water earthworm, there are the following common, widely distributed and large quantities in our province, which are suitable for breeding. Now let's briefly introduce it.
1, gill, belonging to trematodaceae. Widely distributed in all parts of China. Tail-shaped earthworm is relatively thick, with a diameter of about 1.2 ~ 2.2 mm, and often curled. The living body extension length is more than 100 mm, and the fixed specimen is about 30~70 mm, with an average of 53 mm. The living body is purplish red, with more than 185 nodes, with bristles on the back and abdomen of each node. There are obvious annular bands on the X-segment behind the head of mature individuals, which are gray-white protrusions. Starting from the back of the body at about 1/3, there are a pair of filamentous gills in each segment of the ventral line, and the frontmost gill is the shortest and grows gradually, reaching as many as 60- 160 pairs (as shown in figure 1). This is the obvious difference between this species and other water earthworms. The only species in this genus is B.sowerbyi (figure 1).
Lumbricus sushi is mainly distributed in the mud layer of 3-5cm on both sides of the running water in the ditch, and it is still an aerobic species. When living, the reddish tail gills protrude out of the soil and shake up and down with the protruding gills as a plane, with a frequency of about 100 times per minute. When disturbed, the tail gill will immediately shrink into the mud. Under the condition of high temperature or hypoxia, the tail gill extends longer and the gill filament extends wider. The earthworm cocoon of earthworm sushi is oval ... >>
Question 8: Monopterus albus, what food does red-line fish eat? Mainly small miscellaneous fish, earthworms, snails, mussels and so on. Earthworms are the best, and artificial compound feeds such as Daphnia, bean dregs, rapeseed cakes, melons and fruits can also be fed. Pomfret? Pomfret should not be fried with animals; Don't eat with mutton. Fish eggs in the stomach are poisonous and can cause dysentery. Eat small fish and diatoms. Below the front edge, each jaw has 1 row of fine teeth, and the spawning period is May-June. It is distributed in the coastal areas of China, with more in the South China Sea and the East China Sea and less in the Yellow Sea and Bohai Sea. Ecological environment: pelagic fish in offshore area. Often inhabit the slow tidal waters with a water depth of 30-70 meters. Feeding on small fish, jellyfish and diatoms. There is seasonal migration, and the breeding period is from May to June. The number of pregnant eggs is 1 1.7-2 1.8 million, and the eggs are floating with a diameter of 1.6- 1.9 mm. .
Question 9: What are the bugs that are as red and thin as a red line flowing from the faucet? It is the "red nematode".
If red nematodes are found in tap water, the main reason is that the water tank or reservoir is poorly managed and cannot be cleaned in time, resulting in pollution. If users who supply water directly below the third floor find that there are red nematodes in the water, it may be because the summer is hot and humid, which is suitable for the growth of red nematodes. They work and live in sewers and pipes. Every night, they often climb out of the sewer and into the outlet of the user's faucet to get together. When users use water for the first time in the morning, they flush it out, causing the illusion that red nematodes flow out of tap water.
Red nematodes are not parasites, and eating them will not directly harm the human body. However, as the "indicator organism" of unclean water, its existence shows that a certain link of tap water has been polluted by organic matter, and the reason should be found out as soon as possible. After a long time, the pollution will be more serious. If there is only a small amount of red nematodes, the water is not dirty or smelly, and you can drink it after boiling.
Question 10: What happens when the red nematodes in the water eat their bellies?
