Anonymous users2024-02-08Daphnia: Can be kept in large tanks or pools containing organic matter. Daphnia can be used as nutrients in the water to raise water from leftover milk, or you can dig some garden soil and throw it into the water, and some books introduce the use of organic fertilizer (animal manure) as a nutrient base, which is not suitable for raising tropical fish in towns, because it will cause environmental pollution.
Water earthworms: Can survive for several days in old water swapped out of the aquarium. The container for temporarily raising water earthworms should be placed in a dark place, and when the feeding density is large, the water should be changed every day, and the dead insect body should be removed with tweezers when changing the water, otherwise the water earthworms will all die due to the deterioration of water quality.
Blood bugs: Just apply organic fertilizer and seed in the paddy field, and the blood bugs will multiply in large numbers after a few days. At that time, the mud will be scooped up with a fine nylon net, and the blood worms will struggle to drill out of the mud and fall back into the water, and only need to be carried under the net with a container.
Bloodworms are not tolerant to long-term feeding in fresh water, so they are not suitable for breeding at home.
Paramecium: The nutrient solution for cultivating paramecium can be prepared with boiled straw water, put a small amount of vegetable leaves and milk powder (or milk), and after 3 or 4 days, add non-chemical pollution pond and ditch water to inoculate, in a warm environment with sufficient light, a large number of rotifers and paramecium with gray and hazy effect in the water can be seen within a week, and you only need to use a fine cloth to fish out.

Anonymous users2024-02-071) First of all, prepare a container, Zhenwang small jar, pet box, special bottle, etc., you can, the best suggestion is to use a container with a relatively large contact air area to raise the most suitable, because Daphnia will float to the surface of the water to have a similar breathing action, so if the number is large, I am afraid that some will not be able to fight for the position and die.
2) Light source: Generally speaking, as long as there is light, and the light source can not be turned off at night, you can use a small light source, shine, so that you can avoid this trouble.
3) Feeding: Generally, the breeder is told to use yeast powder to soak in water to feed, but if the dosage is not well controlled, the water quality will soon deteriorate, resulting in the rapid death of Daphnia.
4) Daily care: In fact, you don't need to pay much attention to them, as long as you give light and some feeding, you can do it, as for changing the water, every time you suck out the daphnia, you can add the amount of water that is pumped out, if there are too many algae, put some apple snails is also good.
As for the amount of feeding, it should not be too much at a time, but 2 3cc at a time, don't think too little, this is enough, and it will not cause the water quality to deteriorate at once.

Anonymous users2024-02-06When raising fish and insects, it is necessary to prepare a container with a large contact area with air, and ensure that there is a light source for irradiation. Usually feed fish and insects, you can use yeast powder to soak in water to feed, but the amount should not be too much, otherwise it will spoil the water quality. There are too many fish and insects in the breeding tank, so they need to be fished out in time, otherwise it will lead to a large number of fish and insects dying of hypoxia.
When raising fish and insects, it is necessary to prepare a container with a large contact area with air, which can ensure that the fish and insects have enough space to surface and breathe, and also ensure that there is a light source for irradiation.
When feeding fish and insects, you can use yeast powder to soak in water for feeding, but you should control the amount and not too much, otherwise the water quality will deteriorate, resulting in the death of fish and insects.
There are too many fish and insects in the feeding tank, so it needs to be fished out in time, or replaced with a larger tank, otherwise it will lead to too much density of fish and insects and lack of oxygen, and even lead to a large number of fish and insect death.

Anonymous users2024-02-05<>1. Change the water once a week, don't change the water too often.
2. It is recommended to raise or picnic some aquatic plants in the fish tank.
3. Adjust the water temperature to between 20 and 28 degrees.
4. Sprinkle some silver salt every time you change the water to prevent diseases.
5. Keep the fish in a semi-starvation state so that the fish will be more active.
6. If you use tap water when changing the water, expose the water to the sun for three days.
7. Proper sun exposure.
8. The water temperature should be constant.
9. Be careful not to break the eye bubbles when changing the water for the big-eyed longan variety, otherwise you will definitely die.

Anonymous users2024-02-04Fish insects, also known as daphnia, are technically known as cladopods or flexopods. Fish insects are neither fish nor insects, they are a type of zooplankton that live in freshwater, and often make jumping movements in the water.
In the natural environment, fish and insects feed mainly on bacteria, yeasts, algae and organic detritus. To artificially cultivate fish and insects, it is necessary to prepare the culture medium in advance. Take kilograms of fertile soil and 1 kilogram of straw, pour them into a large vat together, add 50 kilograms of water, after full stirring, place them at a temperature of 15 to 18 for 3 to 4 days, and then filter them with gauze, and the filtrate is called the original solution.
Take a certain amount of stock solution and pour it into another tank, and add 2 to 4 times the pool water, so that the culture medium is prepared. At this time, a small number of fish insects can be put into the culture medium, and the water temperature can be kept at 18 to 25 degrees, and the fish insects will grow quickly and will multiply in large numbers to feed goldfish or other fish. In the process of culturing fish and insects, the stock solution should be replenished at any time to ensure that the fish and insects have sufficient feed.

Anonymous users2024-02-03Fish insects, also called daphnia, live in slow or stagnant ponds, feed on organic matter, and the water surface is brownish-red when they reproduce in large quantities, which is a natural feed for fish.
1. Daphnia is simply classified.
Fish insects, also known as daphnia, are mainly distinguished by size and color, and are distinguished by common insects, green insects, and rice insects. Grass worms must be used in summer, and green worms and rice worms can be used in spring and autumn.
2. Grow in stagnant water.
Fish insects most often grow in stagnant water in rice or lotus fields, where leaves block direct sunlight to avoid rising water temperatures, and clear water is best for Daphnia after the water has sunk.
3. Organic matter is food.
Sunlight converts organic matter, which becomes food for fish and insects. The breeze of nature can also purify the water quality, and if the breeze blows, there will be no film on the surface of the water to isolate air oxygen, which will help the fish and insects breathe.
4. Fish and insect breeding season.
Fish insects like to live in very slow or stagnant water, with a depth of about one meter. Every year in late spring and early autumn, it is the season when fish and insects breed in large numbers. Fish and insects float on the surface of the water, often making the surface of the water brownish-red, so it is easy to spot.
5. Preparation of the collection network.
The shank body should be 3 4 meters. The diameter of the net should be small, 20 30 cm is preferred, and the depth of the net is 50 60 cm is best. It is recommended to put a layer of plastic green yarn on the net mask to allow fish and insects to pass through, and to prevent the entry of debris such as aquatic weeds.
6. Daphnia collection method.
Choose a suitable collection point first, and after finding fish and insects, use a collection net to slowly patch them on the surface of the water. This makes it possible to catch a large number of fish and insects, which are then moved into a plastic bucket or plastic food bag with a small amount of water.
1. Bloodworms like to live in the slow flow of fertile water, the late spring and early autumn of each year, is the season of bloodworm reproduction, they float on the water surface, often make the water surface brown-red, this is an excellent opportunity to collect bloodworms. >>>More

If you are careful, have you noticed that there is a language problem in my title, in fact, what I want to talk about is not to directly cool the hamster, but how to provide a cool living environment for the hamster in the summer. The suitable living environment temperature of hamsters is generally between 10 degrees Celsius and 25 degrees Celsius, and if it is too low, it may hibernate and hang up due to heat stroke. The author has lived in Beijing for more than ten years, and I really obviously feel that the summer in Beijing is getting hotter and hotter. >>>More
Methods: 1. The most important thing is to have a set of effective ecological filtration system, including mechanical filtration and biological filtration. Conventional mechanical filtration can only remove solid contaminants, and there are still large amounts of organic matter dissolved in water, such as egg whites, which cannot be filtered out of Pissen, and can only be completed by biological filtration systems. >>>More
As long as the depth of the water is enough for the turtle to easily get out of the water, tap water is fine, but don't change it too often! It should be fished out of the sun for 3 to 4 hours every other day.
