CATDOLL : CATDOLL: Betta fish breeding (breeding bloodworms yourself)

1. Betta fish breeding

Haha! Betta fish are famous for being big eaters among ornamental fish. If you want to keep your own Betta fish well, you can’t use feed. Betta fish naturally love to eat live food! And the diversity of food is also very important! In spring and summer, I usually feed them water fleas (daphnia), water earthworms (nematodes) and frozen bloodworms (bloodworms) because there are no fresh bloodworms in this season. In autumn and winter, I mainly feed them live bloodworms, supplemented by nematodes, and brine shrimp to supplement nutrition.

Hehe, if it's too much trouble, just feed bloodworms! Betta fish love to eat this! It's better to feed twice a day when they are 2-4 months old! Because betta fish eat a lot! And this period is the best time for betta fish to grow! So you have to feed them quickly! HOHO` It's also good to get frozen brine shrimp to supplement nutrition all day long!

2. Which expert can point out the name of this insect?

Nematodes are generally found in sewage and sewers.

This happened in our school before, the nematodes crawled into the water tank on the roof.

When I turned on the tap downstairs, a lot of red thread-like nematodes came out.

Just like you described.

The fish tank you mentioned that has not had the water changed for a long time may have eggs in the water.

Just forward a message and you will understand:

Water storage in midsummer is prone to breeding red nematodes

Generally, disinfection should be carried out at least once every six months; if red nematodes appear in the water, bleaching powder can be used to kill the insects.

Recently, Nanjing has been experiencing high temperatures and heavy humidity, which can easily lead to the breeding of red nematodes. The Nanjing Center for Disease Control and Prevention has received calls from many citizens, saying that "red lines" have inexplicably appeared in their tap water. Experts remind citizens to be careful of the breeding of red nematodes in midsummer, clean secondary water supply tanks or reservoirs in a timely manner, and disinfect solar water heaters frequently.

According to Dr. Ge Ming from the Environmental and Occupational Health Department of Nanjing Center for Disease Control and Prevention, the "red nematodes" are red and slender, generally about 4 cm long, and can be up to 10 cm long. Red nematodes generally live in river water and sewage, and their reproductive capacity increases as the temperature rises. Experts believe that red nematodes are not parasites. Although they will not cause direct harm to the human body if eaten, the bacteria they carry and their excrement can cause gastrointestinal discomfort in people, leading to symptoms such as diarrhea, nausea, and vomiting. At the same time, as an "indicator organism" for unclean water, its existence indicates that tap water has been organically contaminated at some point in the transportation process. Every summer, Nanjing Center for Disease Control and Prevention receives calls reporting that small red worms have been found in tap water.

Doctor Ge said that, under normal circumstances, red nematodes cannot exist in clean and disinfected water. Users who use water tanks or other secondary water supply facilities (such as reservoirs) above the third floor and find red nematodes in tap water are mainly due to poor management of water tanks or other secondary water supply facilities, which are not cleaned in time and cause pollution. The earthworm eggs deposited in the water tanks hatch and develop into red nematodes. Direct water supply users below the third floor find red nematodes in the water mainly because the temperature is high and the humidity is high in summer, which is suitable for the growth of red nematodes. Red nematodes live in large numbers in sewer ditches and pipes. Every night, they often crawl out of the sewer pipes, crawl along the pool wall and the tap wall into the outlet of the user's tap, and gather into a ball. When users use water for the first time in the morning, they flush them out, creating the illusion that red nematodes are flowing out of the tap water. Secondly, if the faucet has been turned on for a period of time and red nematodes are still flowing out, it may be related to the aging and rusting of the water pipes and the breeding of microorganisms in the water, reminding users to replace indoor pipes.

Doctor Ge said that the key to preventing red nematodes is to clean and disinfect secondary water supply facilities such as water tanks in a timely manner, strengthen the management of secondary water supply facilities such as water tanks, and carry out maintenance, cleaning and disinfection in a timely manner. Generally, disinfection should be carried out at least once every six months to prevent the growth of red nematodes in the water; if red nematodes appear in the water, bleaching powder can be used to kill the insects; users living in bungalows and low floors should pay attention to the hygiene of the water environment, keep the tap water pool clean, and try not to place wet objects such as brooms and rags next to the tap water pool at night. At the same time, you can use a plug to plug the drain of the tap water pool; users who have the conditions can also frequently use "84 disinfectant", bleaching powder, bottled household disinfectants, etc. to disinfect long-term wet areas such as sinks and sewer pipes to prevent red nematodes from crawling out. In addition, if the household solar water heater is not used for a long time, the water should be completely drained, and it should be disinfected and cleaned when it is used again, otherwise it may breed red nematodes.

The one centimeter or so you mentioned should be immature, or a shorter variety, especially the one millimeter thick and pointed at both ends you mentioned, which are the characteristics of nematodes:)

The introduction of nematodes in Baidu Encyclopedia is incomplete:

==================================================

Nematodes are not necessarily red. There are black, white, transparent, and beige ones.

Nematodes are the largest group in the soil, and there are so many types.

The most important thing is that yours is thick in the middle and gradually tapers towards both ends, and the two ends are relatively sharp.

This is the most obvious appearance feature of nematodes.

As for what kind of nematode it is, it's hard to say.

And there are no pictures to see

Unless you are a professional in nematode classification, it is difficult to give a specific type of nematode.

3. How to raise betta fish? Is winter suitable for raising betta fish?

Use a heating rod in winter. I have kept betta fish for a long time, but only two of them can survive the winter without heating. One of them died of water mold disease when the temperature rose in spring. If the heating rod is too big to fit, it is recommended to change a tank. Aquarium stores usually sell adhesive tanks of about 30cm, which are cheap and durable. For heating rods, use a 25W mini explosion-proof heating rod of 5~8cm, which is just right for small tanks. If the aquarium store does not sell mini heating rods, go to Taobao to find them, there are many.

Starve your betta fish for a few days and then feed it some food to see if it eats it, or check if the food has a strong fishy or shrimpy smell. That kind of feed is more attractive. If it still doesn't eat, your fish probably only eats live food. Dried bloodworms have little nutritional value, just a layer of skin. If there are no live ones, look for frozen bloodworms. Frozen bloodworms can maintain the nutritional value of bloodworms. Just make sure to thaw them thoroughly when feeding. If not, try feeding dried shrimp (the kind of freeze-dried shrimp that feeds fish, don't feed dried shrimp in the refrigerator). Dried shrimp will swell after soaking in water. The lion king fish I raised before also didn't eat food. I had no place to buy bloodworms, so I fed it dried shrimp. After soaking it soft, throw it into the water and it will eat it by itself. There are a lot of residues. If there is a filter, it's not a big problem.
